My girlfriend and I stayed here for a week. We had a very comfortable stay and would highly recommend the apartment. The apartment itself is super-modern with all the latest gadgets. The guest-room is comfortable and bright with cupboard space and an ensuite bathroom with an amazing shower! It's situated very close to some nice bars and restaurants, to Matadero (for exhibitions, theatre, festivals) and Madrid Rio. The closest tube station is less than 5 minute's walk away taking you to the centre of Madrid in 4 or 5 stops. The guys are very welcoming and friendly. They gave us information about the area - things to do, transport, supermarkets etc. and made us feel at home during our entire stay.
