Nice, clean room in a 5-bedroom apartment that's very central. It's close to many restaurants and bars, and the Antón Martín subway station is just a couple of minutes away. Peralta was very responsive to my messages and requests for help. I would've really liked him to mention that the apartment was to be shared with 2-3 other guests as well as himself and his family. This wasn't an issue in itself, but the fact that this wasn't included in the listing description or communicated upfront isn't something to be overlooked. The address is also different from what's stated on Airbnb, but where you'll probably stay is just a few seconds away. Again, not an issue in itself. About once a week, a maid would come in to clean the room (even if it was locked and you weren't there); decide for yourself whether that's something you'd be comfortable with. All in all, a very good experience at the heart of Madrid with just a few caveats.
