Very very convenient location, just between the two stations of Callao and Sol which brings you to two important metrolines. The host was very helpful and replies quicky, the room was moderately spacious, and everything was clean. The toilet is shared but it was kept in good condition. There is a kitchen and the host also lives in the same apartment. It can be noisy at night as it is at a central location with performers and people around but it is generally a very nice choice.
