The general location of the flat is great. Super close to all the sites, great restaurants nearby, metro a few blocks away. The flat itself is not as “attractive” as the pictures. Moreover, the building felt fairly dicey; so much so that it did not feel safe walking alone. The across the way building neighbors look directly into the main bathroom; the shade is sheer so you do not have privacy. Also, maybe we were there on a bad week, but on two mornings, we were awoken by the noises of the next door neighbor hacking his/her supper up. At the main entrance of the building, there are garbage cans that smell to high heaven…and they are always there. You have to thread that needle as you enter the building. All in all, okay for a couple nights. Rooms are fine. Apartment is clean. WiFi works fine. But I would try to find something else if going back to Madrid.
