I wasn't impressed with the room, not luxurious at all.
toilet seat broken, didn't have hot water twice, neighborhood on a hill and far from all the attractions.
Host was cool when chatting, but in person we shook hands, gave us the key, no map, no advise, no direction to bus or metro. not even propose a glass of water after climbing the stairs to the apartment and 7 hours travel time.
I m sure in 2 days combine we spoke 40 sec.
Coffee machine was broken so the BnB doesn't apply.
if you have a short period of time in room, stay close to Termini station.
