Davidde was an exceptional host. Very responsive to all communication. The location was awesome. My wife and I walked to almost everything: Pantheon, Colosseum, Treve Fountain, Vatican and all in-between. If you don't want to walk, the Number 8 Tram stop is super close and convenient and puts you within very close proximity to the aforementioned.
There are a couple restaurants really close with great food, and when I say close, I mean with 100 feet of the apartment. Also, I recommend taking Davidde up on his recommendation of Grazie and Graziella (short walk down the Travesterre and turn left on Via something something Francisco. It's about a 10 minute walk with hundreds of shops and restaurants on the way to look at.
For groceries; you are also within walking distance to Carefour Express and to another larger store that we saw while walking to Chopstix.
The accommodations were outstanding with separate Air Conditions in each bedroom. They have espresso makers, teas, coffees, sugars, salt, olive oil, laundry detergents towels etc to make your life a bit easier. (You may have to purchase the espresso grounds however, as I am not sure if they are provided or were left by previous BnBers. You also have Netflix at your disposal, which kept our teenagers occupied on those nights just he wife and I went out for dinner.
Lastly, and I put this at the end because there were so many great things about this host and apartment, the only complaint I have are the 3 beds (not including the pull-out-because what pullout is comfortable). The mattresses are not comfortable with the triple threat of being thin, springy (felt the springs) and noisy (hard to be frisky with the kids in the adjacent room). If the host replaces the mattresses with box spring and comfortable mattresses, this would easily be a true 100% 5 Star in my opinion.
