Stayed in this place for three months, December to February.
First the good:
The location cannot be beaten. I'm originally from Madrid but have been away for close to 17 years so I know the place well and seriously, the location is absolutely perfect.
Also, Eloisa (the property manager) was very nice and responsive. A couple things needed fixing/replacing and the process was very smooth.
Now the not-so-good and bad:
The place is packed to the rim with "stuff". One of the things this place advertises is its "charm" and 80s memorabilia. It's true that the artworks add a special touch and that there's a few items of the Movida that are cool to see. But what the ad doesn't tell show is that the place is also packed with old VHS tapes, broken DVD players, old pens, etc etc. At times it feels like living in someone else's storage unit. The couch, office chairs, microwave and bathroom lights were broken.
The radiators are too old and it was SO INCREDIBLY COLD. Had to drain the radiators.
