Riccardo is a great host. His place is very close to Vittorio Emanuelle metro station. We exited on the wrong side so he came and picked us up which was great since it was little late in the night.
Gave us a lot of tips on tourist areas, reachability etc. and also was very helpful.
Just one thing, there is no microwave/stove/utensils so if you are planning to cook, that might not be possible.
Overall, amazing place and great host. Would love to stay again.
