Three of us stayed for 4 nights in the beginning of February in Luca's appartment.
The appartment was surprisingly warm (I feel like there was heated flooring but might be wrong) and its indoor climate was comfortable which can be a problem with ground floor units in old towns.
The location was superb - easy to get around on foot or hop to a bus if needed. I do not believe any metro station was close by - we took bus a couple of times.
One dropback of the place is that it is a very dark place - no natural light whatsoever. One tiny window did not provide any. The indoor lighting could have been done better, too. It is okay for a short stay but I would not recommend to stay longer unless you are okay living in a basement type of dwelling.
The kitchen supply was limited - no cutting board, kitchen/paper towels, only one wine glass, pans are old, a kettle would be handy to make tea.
The sleeping arrangement for the third person is not for everyone. My son slept on the sofa in the living room. Lucky us, he was not fussy but I, personally, would not be happy to have my head resting right next to the entrance door facing street. I would say this is a place for a couple - the sofa in the living space is too close to the entry door to sleep on.
The bed in the bedroom was comfortable.
The toilet had had a broken seat - it would not stay and instead it would move to a side every time you use it. Not a biggy though.
The place was clean.
