The location is fantastic, within 20 to 30 minutes walk from all local tourist spots. I only saw the host when he checked me in. He works, during the day, in the condo, but keeps to himself. The other members of the family, I could occasionally hear, but had absolutely no contact with. I felt safe, and had a great deal of privacy.
The neighborhood also felt very safe.
The bathroom is down the hall, but exclusively yours.
If you have rolling luggage, the train from the airport to Trastevere station is great, but I do not recommend then taking the local tram to the neighborhood. It’s difficult to know where to get off at the correct stop, because the locations of the tram stops are not easily visible, and you have a several block walk on cobblestone once you arrive at the local station. Rolling luggage does not do well over the cobblestone. I would recommend taking a cab once you get to Trastevere station. It’ll be about eight euros.
There’s an app you can download, Free Now (red and white) that will call a cab to meet you at your location. This comes in handy, if you get lost and need to call a cab to come and find you or you need to get somewhere quickly.
If you need it, remember to turn on the air conditioning when you arrive. The remote control is in the box next to the bed. I also moved the chair by the wardrobe to the corner table so that I could create a desk to use while I was there.
