The apartment is superb and has an excelent location, there are a lot of places to eat nearby. Moreover, it has a kitchen to prepare caffe or other simple meals.
You can walk to most of the major churchs, musemus, and other attractions (as we did) or you can use the tram, which has an stop right in front of the apparment.
The place has everything you need, we were a group of 4 and we didn't have any problem with the space or the beds.
I totally recommend it!
