This stay was a little traumatic.
Entering the flat, a dog welcomed us shouting like crazy, and didn't stop growling against us for 3 days.
The flat is like the photos, good quality.
Position is ok, definitely not one of the nicest areas of Madrid but it's good if you come from the station.
The landlord told us we were noisy during the night once (the walls are super thin so I guess that's the thing) but then the dog is super noisy, we heard the vacuum in the early morning, the neighbors working to renew their flat and every other noise that woke us up multiple times every night.
The room is quite cold in winter and the heater is centralized so we couldn't do much. I asked for an extra blanket and the answer was "you've got two over the bed". Of course I do (even if the second one is super small), but what if I'm cold anyway?
The entrance gate is clearly damaged and once it took 15 minutes to open it, as the keys wouldn't slide the right way.
Not recommendable at all, I'm sorry.
