The apartment is brilliantly equipped and is in a perfect location. It is just off the main high street of Madrid(Gran Via) and is yet in a very quiet street with no disturbances. Matias is a very welcoming host and was very easy to communicate with. We really liked the apartment and after the first 3 days stay we traveled outside Madrid but had to spend a night in Madrid again for the flight and chose Matias's apartment again. Highly recommended.
