We got the key to the Appartement from Matteos mum who was very nice and showed us the apartment and told us some things about the kitchen (in Italian, but we got most of it).
The whole apartment was very nice and clean. The room was more than big enough for the two of us. Although the room was next to a big street, you barely heard the traffic inside while the windows were closed. We only heard the people from the apartment above quite a bit but that wasn't really a big deal for us.
The kitchen and one of the bathrooms seemed to been renovated not long ago. The kitchen had everything you need, but, unfortunately, when we arrived there was not much there for breakfast.
In the Appartement there are in total 4 rooms that are rent to other people and although there were people in all other rooms we barely noticed most of them and there never was a problem with getting into one of the two bathrooms. The people we met were very nice and friendly.
All in all the whole Appartement was nicely done up and the stay was very comfortable and nice, we really enjoyed it.
