We had a really great stay here. It's in a great location near lots of tapas spots and bars. Madrid is fairly compact, so it's easy to walk to most areas of interest from here. The flat is nice and clean and seemed newly refurbished, though it's a little tight on space. (More than 2 people might be too cramped.) The street outside is pretty lively Thursday - Sunday, but the doors shut out noise very well, and we slept very well here. The A/C worked great too. We didn't meet Cristina, but her helper Agustin was really nice, even though we got in VERY late due to flight issues. Overall, I'd definitely recommend a stay here.
