Marguerita was a true partner in our families success in getting our new home. She handles everything with grace and confidence, making the purchasing journey a pleasure for me.

I will recommend her always, her skills should be shared with others in her field, she would be an incredible mentor and example of how real estate sales should be done.

Our greatest gratitude for this very special person.

Marguerita went well above and beyond the call of duty. Super professional, sold our property extremely quickly despite a somewhat challenging situation. We got what we expected in the sale. She also was an excellent coordinator when it came to needed repairs, cleanup, and the last minute repair needed due to storm damage hours before the closing. If everyone worked as hard, was as attentive, and as professional, focused, and genuinely nice as she is it would be a better planet. We are extremely happy.

I interviewed three brokers and almost instantly knew Marguerita was the person I'd go with based on her experience and knowledge of the area. I also felt she was genuinely honest with me, she was very professional, came prepared, was an excellent listener and really cared. She was on top of every aspect of selling the house and a wonderful guide and support during the entire process.

My overall experience was excellent regarding her support, character and success of selling the house. I wholeheartedly recommend working with Marguerita.

We've been looking for a property for a while now. The one thing that you can't account for is all of the local knowledge and information that only someone in the area can bring. As we worked through our purchase, Marguerita was able to answer so many questions for us, so quickly, it helped keep the transaction operating smoothly. Marguerita came highly recommended to us and we were not disappointed. She was always willing to answer questions and get on the phone with us when we needed it. We feel that Marguerita is incredibly detail oriented, trustworthy and hardworking and we would feel comfortable referring her to our closest friends.

I would never use any other agent to sell or list my property. Marguerita's main concern is her client's happiness over any sale. She is a class act! Extremely professional and organized..and she has a lot of integrity. I have had multiple transactions using her and it is why I always go back to her!!

From our first phone contact, without any obligation on our part, Marguerita was helpful and informative and did not pressure us in any way. When we first met face-to-face, she was accommodating and knowledgeable, and she was excellent in every subsequent encounter.

Absolutely perfect!

Everything went smoothly, thanks to Marguerita.

We were selling a family home in which we had never lived, so we needed guidance in cleaning out the house as well as preparing it for sale. Marguerita was immensely helpful in giving advice, suggestions, support, always in a friendly, intelligent, non-judgmental manner. Because it was a probate sale, Marguerita had to communicate with an attorney, and she did that efficiently and thoroughly so that the many legal issues were dealt with appropriately. Truly, every step of the way, Marguerita made it easy for us. She is a consummate real estate professional. We highly recommend her.

Marguerita is a real asset to C21.

Marguerita Castanera is a caring, yet sharp agent. She understood the current buyers' market in Sonoma Valley. Her attention to what we were looking for, and more importantly, what we were not looking for, was amazing. She found us the perfect property at the perfect time to allow us to be a competitive bidder and future homeowner. The timing was amazing, and the process MUCH more pleasant than our experiences with other agents. There was zero pressure. We were 100% informed, while guided to do whatever made us comfortable in everything from the bidding process to escrow details.

Having recently experienced the bidding process with another agent, we knew very quickly that our experience with Marguerita was SO much easier and pleasant. I am a very happy and satisfied customer and will recommend her highly to anyone interested in buying or listing a home.

Having previously bought and sold real estate in Sonoma County several times, we thought that we knew what to expect from our broker in terms of commitment to our transaction and to the sale process. To our surprise and gratification, Marguerita Castanera set new standards for customer service. This was not an easy sale but throughout the process we were kept well informed; our approvals were obtained with consideration for our time and convenience; and her suggestions about how to market the property and address issues that arose were invaluable. We would not even think about using someone else after this experience.

Marguerita was always positive, upbeat, with a can-do attitude. She listened carefully to what I needed and helped guide me through the process of selling my house by setting clear expectations and providing very clear communication at every step of the way. Marguerita was willing to try creative approaches when they were called for and we ended up with a very satisfactory result.

Marguerita helped us sell our mobile home in Sonoma. We knew she would do a good job for us as buyers, too.

We worked through a few glitches early on with our lender, but it all worked out. Marguerita did a fine job coordinating with our lender who was out of town and "online" primarily.

I wouldn't hesitate to recommend Marguerita to other sellers and buyers.

Marguerita went above and beyond to make sure my condo sold at a good price and in a timely fashion. There were some challenges with the HOA and she consistently was in contact with them and helping the issues to get resolved, there were also issues with the buyers' lender and she also stayed on top of that, she worked very hard in showing the condo, dealt with different offers, and is a joy to work with and be around, very fun yet professional. I recommend her all the time to people selling/buying property.

Marguerita was an absolute joy to work with! Since I wasn't very familiar with Sonoma, she took the time to drive me around and inform me about different neighborhoods. She was very helpful with my decision about where to buy. She also educated me about local restaurants and shops, which will be so helpful when I live there.

Marguerita's manner was always calm and gracious even in the most stressful situation. It was quite amazing to observe how calm she stayed. I really can't say enough positive things about her professional yet super friendly manner.

I give her rave reviews to all my friends and would recommend her to anyone.

Thanks Marguerita!!!!

Marguerita didn't miss a beat. She followed up on all details and provided us with excellent service. As an out of town seller and buyer in Sonoma, I was very satisfied with her help. We could not have done it without her.

We were influenced by the Marguerita's professionalism and sincerity when she was contacted with a "we need it now" request and responded with courtesy and willingness to help.
