The apartment is located perfectly central and right next to Plaza Mayor. Although there was a bit inconvenience with the check-in due to a wrong access code, and due to the late hour of our arrival it wasn't possible to receive any support at that time. On the cold arrival night, it wasn't possible to turn on heating from the A/C unit by following the given instructions, which we later found out was due to a breaker-switch being turned off in the fuse box, and not supposed to. The apartment itself is looking modern, but with minor deficiencies present - I.e. the sofa bed in the living room has definitely seen better days, and the frame of the bed is broken, which makes it sink in the middle.
All in all, the location of the apartment is its biggest strong suit, and I'd say that it is more suitable for friends who can adjust to the minor but still unexpected inconvenences, rather than for families with children, who may not be able to do so.
