The location of Guille's place is fantastic, 5 minutes to La Latina, 20 minutes to Mercado de San Miguel and about 30 to Malasana. The apartment itself is clean and nicely apointed, the one thing I'd mention is that the apartment seems bright and sunny in the photos but this isn't the case, the ground floor windows look onto a small courtyard which doesn't seem to ever get sun so you'd need a light on even when it is blue skies and sunny overhead.
