My three friends and I had a wonderful time staying at Lina's place! You can tell right away that the apartment has a lot of soul and love put into it - it is beautiful, spacious and best of all, it is located in a fun/centrally located neighborhood on a quiet street. Added bonuses - the beds were comfy and the kitchen was well-equipped if one wants to do some light cooking (which we ended up doing one evening). Check-in and check-out were clear and simple.
I would absolutely stay here again if I return to Madrid!
