The location is awesome - close to a popular metro station, close to a supermarket which works until late and on Sundays, close to the ideal city centre, close to a locker storage. The check in is very easy and communication with the host is fast and accurate. He even gave us tips on where to store our luggage for a day. The apartment is well taken care of. It is clean and comfortable. The only issue we had was with hot water, but only in later evening. The apartment has a well equipped kitchen so you can cook something little. The place fits easily 3 people and there is room for one more person. It is not noisy so you can get some rest. We enjoyed our stay and the communication with the host. The only thing that would be even greater is if there were some tips left on a piece of paper, because there is so much going on in Madrid. Other than that, the apartment is great with an even greater location.
