The host was great and easy to communicate with. The flat is also very nice, clean, and well equipped. However, the localiazation of the flat is not so great. The flat is located very close to the metro station and a supermarket but the area is quite dodgy. The flat is located on the first floor above two restaurants, which means you can smell it quite often. The street is very loud with people singing (mostly in spanish) throughout the night. It might be better suited for a stay during the winter as one could close the windows and potentially less people would party outside.
To sum up: a very nice flat with not so nice location.
