I really enjoyed staying here for nearly 2 weeks; the location is fantastic and, while it is very noisy on the streets, the bedroom is quiet and the heavy wooden balcony doors reduce the noise so much. I was pleasantly surprised, as a light sleeper, and never needed earplugs as I have in other places in Madrid/Barcelona. There is AC in both the bedroom and living room, which is amazing for Madrid's heat... and also helps if you hear street noise. Apartment feels safe, esp in such a busy area. Everything was very clean and Liliana was helpful in meeting me at an inconvenient time (although there is a fee for a late arrival). If you arrive by plane/train/bus, this should not be a problem with a set schedule; but i had an unpredictable arrival by car and so I ended up paying a rather high late arrival fee (which is detailed on the description, so I knew this). Overall, this was a great place to stay.
