We actually thought it was a very nice space and seemed very clean. We did have an issue and question at the outset and sent a message. We got a quick response a couple of times, but it was an automated response saying the host had received and we would get a reply. We sent a response asking about a smell we noticed immediately upon arrival and suggested it smelled like bug spray and asked him if there had been any pest issues. We got one of those automated responses saying we would get a response later. We also told the host that we really did not want the "concierge" coming in every day to clean. We are pretty obsessive about cleanliness, and always sanitize the kitchen and bathroom regardless of how clean it appears. I should also add that we did not intend to cook while there, and we did not do so, but that we said we would dispose of any garbage - which we did do. We were there basically to sleep and were using Rome as a base camp this time to visit surrounding areas.
The second night we were there, my wife walked into the bathroom in the middle of the night and turned the light on. A roach scurried around the middle of the floor and disappeared under the toilet. This does not work for us. She couldn't catch it, and we later saw a small opening between the wall and the floor right under the toilet; we assume that is where it disappeared, but we do not know. We did keep the lights on in the bathroom during the night from that point on, and we never saw another roach. We then contacted the host and conveyed this incident, and he did sent us an email saying that was largely implausible as they have a "concierge" service, although roaches and mice were everywhere in the world and also noted that sometimes another guest may let a bug in.
We did like the unit itself and are hesitant to mention - truth is, there was a roach - saw one, only one.
We were for the most part pleased with the unit. It DID appear to be clean and cared for and, other than the bug situation, it was fine. We did not cook there, so we can't speak to that. The host has excellent reviews, as he quickly pointed out to us. Just speaking the truth about what happened and wishing him the best.
