The apartment and its location are great! Walking distance to Gran Via and all the restaurants, bars and shops around Chueca and the center of town. I would definitely stay there again, the only improvement I would suggest is having basic kitchen items available for the guests, I had to buy everything from salt, oil, napkins, etc.; would be great to have those basic things available already.
On a separate note, and this is not related to Raul or his apartment, there’s a lot of renovation work happening in other parts of the building. This means construction noise, workers and the normal construction mess in the entrance and stairs.
