We stayed for a week in the apartment of Jorge and Maria Jesus. The location is very good, 3-4 minute walk to the metro station and a big 24h open supermarket. It takes about 15 min. with metro to the city centre. The neighbourhood is pretty quiet, but - as other guests also mentioned - there's that garbage truck in the middle of the night. About 50 m from the apartment there's a restaurant with great Spanish food, nice wine and beer, very affordable and the staff is really friendly. Locals are even in line for a table at lunch time.
The apartment is very well equipped, the bed is good but a little bit small for two persons. The shower is also a little bit small. There is more than enough hot water for showering and washing up. WiFi is fast.
Jorge and Maria Jesus are really nice hosts, although we didn’t meet Maria Jesus.
The communication with Jorge went very smooth and he explained how to get from the airport to the apartment the easiest way. We had a great stay / experience in Madrid and will definitely come back some day!
