I stayed 7 days in September 2021 in this apparement.
The appartement is located is a livery area at a 20 to 30 minutes walk from the Duomo. The walk is pleasant since it is paved with a lot of shops, restaurants and bars. It felt wat more authentic & more italian than the city center and I absolutely don't regret going there. In addition, the flat is very calm and there is a large supermarket at a 2-minute walk.
The host was answering fast to any of my message, and was helpful with the check-in / check-out. The flat was clean. A few vegetables from the hosts' grandparents were left - it is a nice welcome gift! There are not a lot of dished but it is somehow sufficient for 1 to 2 persons.
I did not give a 5 stars review for 2 reasons:
1_ The flat lacks of light, even with a sunny weather and all windows opened. It is not a problem at all if you plan to only get a few meals there and sleep, but if you wish to live in the flat for a longer stay it can be a bit depressing.
2_ The second point is more subjectif: there is no sofa or armchair and I felt it was missing to read / chill.
Hope it helps!
