Sara's apartment is perfectly located if you're a solo traveller or a couple and are looking for clean, functional accommodation in Centro. Most everything on the tourist map is within walking distance, the area is very safe and the 24x7 Carrefour just outside makes life very easy. The apartment is over 2 floors, with the bedroom and bathroom on the level that you enter, while a staircase takes you to the living areas and kitchen. Everything worked as indicated in the listing and it does serve as a very convenient base to explore Madrid.
