We stayed in Federico's apartment for 3 nights. This apartment has 10/10 location. In the city centre, close to railways station. The apartment itself is really nice. New bathroom, big living room and well equipped kitchen for a short stay. On the other hand there were small issues. 1) Federico speaks only italian, but you can translate and his response time is not that quick as you would like to
2) Hot water - you need to turn on the switch in bathroom the heat up the water. Federico did not tell us this, so first night we stayed with only cold water, which is not great especially in February. When the water is heat up, you have only 3 mins until the water is out, then you need to wait again.
3) You may feel disrupted from the noise outside, because the balcony door seals badly. So it was like we had the door opened all the time...
Overall our stay was great. This is a honest review, so thats why I pointed out these small issues.
