This place is perfectly clean. Now smoke smell which is in a lot of Italy. It was a nice taxi ride from train but after that walkable I would say if you are slower or senior you would want a taxi into the city area; but there's a taxi stand just a block or two away.
For american travelers: the residential area is like a "Beverly Hills" with men in beautiful suits and well adorned women. We very much stuck out as tourists.
The tips for dinner were amazing. Except baccano by trevi fountain. I would skip that all together. Touristy and average food.
We did have a plumbing issue with a sink that didn't drain but that's to be expected. Otherwise a very nice place.
I would definitely book again.
