The stay at Federico's place was in general ok.
The space is enough for two people (I wouldn't dare sharing this small studio between 4 people). Location is really good, with shops around and just a short walk from the city center.
Unfortunately I found cleanliness to be less than ideal: I kept finding long hairs from a previous guest, and the drain in the shower was clogged.
There is an Asian restaurant next-door, and the smell of fish was just nauseating around noon.
