The best thing about this place is its location. All the major attractions in Madrid city center are within 30 minutes' walking distance. Lots of restaurants, bars, and cafes in the area. The host was very helpful and responsive.
The apartment itself needs maintenance. Misplaced floor boards and a strong stink coming from the toilet most of the time. Dirty and mouldy in the bathroom. Since they are charging a cleaning fee, they need to do better in this regard.
It can get noisy with the neighbors as the walls are very thin and sometimes it feels like you are sharing the apartment with all the neighbors. Most basic utensils in the kitchen. Suitable for a few days' stay.
