The flat is in an amazing location, walking distance from everything. The pictures are very accurate. Its easy to reach by metro/renfe from/to the airport.
The owners asked us to take the rubbish out before we left (despite paying a cleaning fee). Opening the door was tricky (make sure they show you how to open it). We had to call the emergency number they provide but they didn’t reply, however they quickly reply to messages.
On our last day, we used a public locker (for €9) all day to keep our bags since the owner offered a very expensive deal to do a late check out.
