We stayed in the apartment for about 5 days and immediately we felt like we were in ours. Very friendly welcome during the check-in from Barbara and Ignacio (who gave us valuable information) and really flexible, as our flight landed later on that day. Also, check-out was pretty easy, if you have an early morning or night flight.
The apartment is as it looks on the photos, exactly 100% - For two persons is perfect. Clean, renovated and absolutely cosy - with very warm and modern decoration.
We enjoyed our stay and its location is perfect as you can walk around the main sightseeing points easily in 10-20 minutes by foot. The neighbourhood is nice, near a square where you can find anything (restaurants, bars, supermarkets, bakery etc). Very close to Lavapies and other small neighbourhoods where you can enjoy Madrid's sightseeings and nightlife.
Definitely we'll come back to Madrid (we loved the city), we wanna stay in Sara's apartment. :)))
