I definitely recommend you stay here!
Good price, excellent service and super hosts.

Carlos and Frank are great hosts, everything was exactly the way it is described on Air BnB. The apartment is located in the city center, we spent 4 days in Madrid, and from here it was very easy to find everything that I wanted to check (sightseeing, famous squares, parks, monuments) on foot, so we did not use any public transport to see the city.
The flat is super comfortable and very clean, well equipped (microwave, cafe machine, TV, radio, shower gel, shampoo, kitchen stuff, hair dryer...).
Frank allowed us to stay after check out time, and we could left our baggage in the apartment until we had to leave for the airport. This was also a huge help for us.
