Daniel's place was in a great location right next to the metro Lavapies but we never needed to take the metro. Everything was within a 15, 20 minute walk. There was also a 24 hr market right across the Airbnb.
Despite the fact that it was located in a busy area, we were on the 5th floor and even on a Friday night we were able to sleep without any problems. It is very peaceful at night.
The room is large enough to comfortably fit two full size beds and a desk. The room and bed sheets were clean and they gave us fresh towels to use. The bathroom was also very clean as well!
If we were to come back to Madrid we would definitely stay here again!
