The apartment at Atocha 55 is extremely well located, right in the city center, with lots of restaurant options. The apartment is spacious, bright, well appointed, and has a very comfortable bed and nice shower. This is one of the nicest one bedroom Airbnb I have seen in Madrid. The only thing to have in mind is that the area is a bit noisy at night. Soundproofing in the apartment is OK. We had no issues with it, but it's something to consider if you are a light sleeper. Check-in was easy and Daniel and Sandra respond messages promptly. I highly recommend this place and will return.
