The apartment is in good location, about 10 minutes walk from the duomo. The kitchen has all the utensils you need, and the host left a small water bottle for each one of us in the family. The kitchen is small..2 electric burners only so can be challenging if you are planning to cook big meals.
The rooms are small - the beds pretty much take up the entire room. There is tv in every room, the AC worked fine, though wifi was slow. It worked fine but would throttle when everyone was on their devices. The sofa bed was not comfortable, ok for my son to bear it as we were there for 2 nights only. The check in process is self check in, but the host provided pretty detailed videos so not a problem. We were able to get in an hour earlier but it did require a lot of asking and did not get a late checkout nor were allowed to store luggage. We needed 1-2 hours of time for luggage on checkout day but were politely asked to look for storage at the train station
I would recommend this apt. if you are in town for a couple of days and need a place near the duomo.
