Paula's apartment is even more lovely than the pictures show. I stayed there three nights with a friend and we absolutely loved it. Paula and her boyfriend were more than welcoming, helped us with everything, left us breakfast and told us where to shop and eat. The part of Madrid where the apartment is located, is fantastic, very central, easy to reach from the airport/train, and has lots of great shops, restaurants, and bars. The apartment can get a little bit noisey-ish in the mornings during a weekday, since it is facing a street, so if you have a light sleep, bring earplugs :). We would definitely go back and stay at Paula's apartment, due its location, the very nice hosts and the fact, that you feel instantly at home in this lovely apartment.
