Roberto greeted us on arrival and gave us a very warm welcome. He was a star and made us feel very comfortable, answered all our questions quickly and went above and beyond to help us local tips/amenities.
The flat beautiful and very spacious. It is very well equipped although there is no washing machine but they offered laundry service at no cost. It is about 10 minutes away from the nearest metro station which takes you the city centre in about 30 minutes (±10 minutes depending on how fast/frequent the trains are).
The only issue we had was the air conditioning, it is very hot in Madrid but the air conditioning barely worked - it was not very strong and did not cool the space to under 25 degrees. It was very warm at night especially for the room right at the top we had to move to sleep on the sofa as the air conditioning was not able to cool the area. The air conditioning also did not stay on, we left the flat for a short 40 minute trip for a snack around the corner and when we came back the air conditioning was switched off. This meant we had to wait hour or so for the flat to become a bearable temperature.
Overall we enjoyed our trip to Madrid. It was a very trendy flat and Roberto could not have been kinder.
