I had the pleasure to stay for a full month and my experience exceeded my expectations. I was greeted by Enrique at a time convenient to me and given a tour of the place and useful suggestions from a local and foodie's perspective (included in their booklet). Throughout the month he was always available and quick to reply to any questions I had, you can tell they genuinely care about their guest's comfort. Once there was a small issue in the apartment and it was fixed in a short time frame. I noticed another review someone complaining about the street sounds - but I think that's expected anywhere near this bustling city and especially in a hip party area like Malasaña. I personally was able to sleep quite well especially with dark the apartment can get with the blinds down. Would recommend this place!
