Domingo's apartment is a very nice and clean space to stay. Even if it is small it is extremely well equipped. The location is a little bit away from the city center(15 minutes by public transport) but really easy to find and be transferred. The only disadvantage was that the apartment wasn't ready at the time that we have referred for the check in. We were there at 14:00(as we had said to Domingo) and we were waiting for 1hour and a half in order to be cleaned.To sum up, it is a nice place to stay in Madrid!
