We loved this apartment and Madrid, too. Sol met us when we arrived at the apartment, and she's very kind and friendly. The apartment was in the perfect place- a lovely, quiet tree-lined street with incredible views from the balcony (where we sat outside every day in the sunshine) of the ancient Church of San Nicolas and, in the distance, pine trees and the dome of the Catedral de Santa Maria. It is very close to Opera and Sol metros, but really, we just walked everywhere- Malasana, Chueca, La Latina, everything is nearby. The bed was very comfortable for sleeping and the linens fresh, soft, and warm. You can control both heat and air, but the temperature was great for us in March and we did not use it. We did use the little espresso machine every morning. Within a block in either direction you can get croissants, and delicious palmeras, etc, and there is also a small 24 hour grocery nearby on Calle Mayor. I can't overstate the peacefulness and beauty of this spot. In short, everything is nearby, and everything is lovely. We would be glad to stay here again. We miss it already. Thanks, Sol!
