We were a group of 10 People and we had an amazing stay.
Miguel and his partners were always reachable, of a good help. The communication with him was easy and pleasant. The flat was really central, with underground stations close by, Gran Via was 2min away. It was really a perfect location. The flat was big, modern, well equipped , really smartly furnished. The 2 master bedrooms were quite nice. The living room was cozy, and beautiful, with a big flatscreen TV and a Playstation and Netflix installed.
All in all, this was an amazing stay and I would highly recommend Miguel.
