Juan was a great communicator and his apartment is fantastic. The location can't be beat. Be aware that it is on the 5th floor and there is no elevator--it's a trek to get up those stairs! The place is ideal for 2 (we spent 4 days with just 2 people and then 3 days with 4 people, which felt pretty cramped with all of us in there at the same time). I will definitely stay again if I am in Madrid.
