This is a real catch.
Host: Giorgio is super helpful, the communication was smooth and he helped us with recommendations to make our stay in Rome as smooth as possible
Location: 20-25 minutes walk from Vatican Museum, next to a metro stop and close to buses. Plenty of options to have a drink or to eat nearby, shops, markets (there's also a mall really close but didn't get to go there since we had pretty much all we needed at the local/ smaller shops).
Do not miss the icecream place nearby, possibly one of the best icecreams I've had in Rome
Appartment : comfortable for two persons, I think 3 would also fit well (supposing you're not in Rome to stay in the apartment all day). It has all the amenities one would need for a short (even a longer stay) and is located in a quiet building.
TLDR: great host, good location, nice apartment; would definitely stay there again!
Thank you for everything, Giorgio!
