I stayed for 2.5 weeks and was very comfortable. The location is excellent, and I was able to walk everywhere. The building is clean and safe with friendly door-men. I stayed in November, so was grateful for the flat's wooden floor (instead of cold tiles). The wifi was fast and the TV worked well, so I could practise my Spanish. It is an interior flat, which means no natural day-light. This did not matter as I was out all day; the flat was warm in the evening, and I imagine it is pleasantly cool in the summer.
