The location is fantastic, could not be better for exploring most parts of Madrid by foot. Restaurants, shops, bars and many sights are really near and the atmosphere of the area is very nice as well.
The apartment lacked a bit of care. The curtains were mixed matched and did not cover the windows well, there was no shower curtain, the sheets of the previous guests were left hanging in the spare room, some furniture was quite damaged and the we had plastic ikea storage boxes for bedside tables… with a bit of love and care the place could really feel much more welcoming.
In any case we had a good trip and if you don’t mind these details, and spend most of your time outside, you will be able to really enjoy Madrid from this location.
