the apartment is situated in the best area of Madrid. I've lived in the same street for 6 months and I can guarantee that there's no other zone you'd like to stay during your trip.
Well equipped and warm. Wifi and HI-FI stereo too! perfect to warm up before the party!!
The host was very welcoming and nice. He can give you also good advices where going to eat etc...
I really suggest to spend your time here when you go to Madrid!
