The apartment is very well located, but in an older building with some of the issues that come with that. The front door to the building is difficult to open, and requires patience and a bit of luck to get the key to turn properly. The walls in the studio are paper thin, and you can hear everything the neighbors are doing and saying next door. It was difficult to work from the apartment in the evenings before dinner because of the noise levels, and we were woken up three nights in a row from them coming home between 3 and 5 am drunk and arguing. The apartment is also very cold and does not retain heat well, and there is not enough hot water available for two people to take comfortable showers. The apartment shows slightly better in the pictures than reality. There is less natural light and the space feels smaller in person, and although renovated with nice design touches and equipment, some of the furnishings are worn and old. The bathroom sink handle seemed to be in need of repair, so we had to use the kitchen sink, which had what appeared to be black mold in the corner. We were looking forward to our stay in this apartment based on the photos, description, and other reviews, and in general Enrique is a very helpful and accommodating host, but we would not recommend this apartment for a couple and/or a longer trip. It would be good for one person who is not planning to be in the apartment much for a night or two during a warmer time of the year in Madrid.
