I am in a bit of conflict writing this review, but it's mostly positive.
Firstly, let me say that Francesco and his partner (didn't get go know her name) are tremendously kind and responsive. Since months before check-in they were attentive to anything needed, they replied quickly and kindly every time, and I felt like I could turn to them if anything happened! I couldn't ask for better guests for my arrival to the fist city in my itinerary. They had a little basket with snacks waiting for me, which is such a nice detail since I didn't have the energy to go to get food!
The apartment is small and nice, and right next to a metro station which led me to the city center in less than 15 minutes and to the station in about 30. I'd say that's a luxury! Pro-tip for new tourists: you can pay the transport with credit/debit card directly, no tickets needed :D
On the bad side, the bed is not very comfortable as it is a futon, but since I'm small it wasn't really a problem for me. For heavier people it might be a problem so keep that in mind. Also, there is a blocked door that leads to their apartment and that I wasn't aware of. Not really a problem, but it also means that you can easily hear to almost anything that happens there. If you are a light sleeper or easily stressed by noise it could be problematic. I am, and because of that I am used to carrying ear plugs around, but I could still hear to outside noises.
Keep in mind that at the time I am writing this, there are reparations going on on the building's facade so there is scaffolding on the terrace. Pf course Francesco kindly let me knows with anticipation and even gave me a discount!! What he couldn't warn me of was of the worker knocking on my window at 8:30 am to ask me something in Italian. Luckily I was already dressed because I knew beforehand that someone could appear on the window and decided to wake up early, but having a man outside a window with only lace curtains, able to see where I stored my things and when I went out, made me feel quite unsafe. Again, not something Francesco could anticipate, but if the closet that has a key actually locked, it would have helped.
In conclusion, mostly a good place and at a good price, but if you especially want silence and privacy, perhaps give it a second thought.
Best wishes to Francesco and his family!
