Well located, small flat, suitable for a couple or individual traveller, around the corner from Colón underground station, and near the main Paseo de Recoletos. Flat, however, is on the other side of the building, so traffic noise isn't really an issue. Decently appointed and as described on the website. Good for self-catering, with some nice touches too (Nespresso machine and box of capsules, bottle of red wine on arrival). Clean, with a comfortable bed. Bathroom a bit worn, but good shower. Only very slight hitch was the man on the desk (this is a building with some permanent residents and some short-term lets, in a total of 300+ apartments) not knowing anything about my arrival, so there was a little bit of confusion before I spied an envelope containing my keys in the pigeonhole of my flat number behind the desk.
