The location of Nuria's apartment couldn't be better--located a 5 minute walk from the Callao metro station and a 12 minute walk from Sol. The street Nuria lives on (in Malasaña) is beautiful with lots of shops, cafés, and bars and a grocery store right next door. Walking 5 minutes in the opposite direction of Sol leads you to Chueca. Nuria was very quick to respond to any questions. I would definitely reccommend a stay in her flat.
