During our stay we mostly dealt with Julio - Diego's father, who is retired and always at home, so you can arrive pretty much any time as well as leave your bags on the day of departure and pick them up later. Julio was super friendly and talkative and gave us some tips about places to eat as a local. I absolutely loved the room - it reminded me some cosy summer house and that is in the very heart of Madrid! The location is indeed in the walking distance to main highlights. It was probaly my best Airbnb stay so far. Thanks Julio and Diego!
