Pros:
Excellent location - like 10 steps from the Duomo and all the restaurants. 10-12 min walk from the railway station. 2-3 min walk to David. Walk to everything, come back when you need a break.
Suite is almost brand new / recently renovated, with high end finishings, large marble washroom etc luxury features, high ceilings and is quite large for a studio.
Building is very nice, safe, secure, new elevator, etc.
Host let us check-out about 45 min late, and that was appreciated.
Good comfortable mattress
Cons:
There is no wifi, and cell phone signal is very weak inside the unit, and that made it difficult to communicate with the host.
Check in experience was not great. Seems to be outsourced to a third party who had no idea about the unit, how to work the air conditioning unit (which is a bit complex and in Italian). Was not very welcoming and rather curt. Just wanted to collect the tax money and leave.
We had to walk out of the building to get cell phone signal and then contact the host, who did promptly send someone to help adjust the air conditioning. The host could consider leaving a booklet or print out of instructions for appliances in the room.
There is no dishwasher, or clothes iron in the room.
