The apartment is nice and it is located near several strategic points such as the Atocha station and Lavapiés metro stop. The flexible check-in it is appreciated. What we didn't like is that the description states that it has WiFI and it doesn't. The host told us about this when she gave us the keys and we would have liked to know it beforehand, given that WiFi is a key feature for us (the signal inside the apartment is really bad and I had to buy a chip to be able to communicate with my family and friends). Even with a chip, you have to go outside the building to communicate because of the signal. Beatriz was a kind host but we think that communication of missing/broken features should be included.
