We didn't meet Andrew himself but he answered really fast when we had some electricity problems in the apartment, check in and out also was really easy. The location of the apartment is absolutely gorgeous but even though you don't hear any street noises the apartment is a little bit noisy during the night since you hear the elevator/apartment doors/neighbours in the hallway very clearly. Furthermore it wasn't too comfortable that we didn't had a real bed but a slanting couch. But anyhow we had a great stay in Madrid due to the location of the apartment
