Good value and a very good location. A short walk down hill to the Puerta de Toledo Metro and a slightly longer walk (say 3-5 minutes) up the hill to the La Latina Metro station - both on line 5. A few more minutes walk gets you to the Tirso de Molina Metro station and the line 1 trains. With 5 people there was still enough room. The patio is very nice.
The apartment was generally quite quiet, even with some windows open at night. There is a club in the next building that had a big line outside one night, but we could only hear the people waiting to get in when we were outside on the patio - we could not hear the club's music.
