Beautiful apartment in the center of the hip area of Madrid, close to lots of great shopping and food. Gorgeous building, very clean, air conditioning worked great. The host has a lot of rules, so if you are worried I'd ask for those in advance, none of them were un-reasonable. The toilets are weak in their flush and there is a fee if you cause a clog, so I would recommend flushing often. Don't be scared if the toilet stops flushing, you have to wait about 15 minutes or so for the tank to re-fill on its own between flushes. The apartment was very beautiful and clean and a joy to stay at.
