Location location location! This place is great, walking distance to everything. Food, rest, bars (if you are looking for that), supermarket, Eataly, metro, train station, entertainment, etc.
Garibaldi Metro is a few steps away. Food right outside (next door) and many places to choose from all around a walking distance.
Host had someone meet us at the train station to make sure we came found the place, after waiting for a couple hours (aiport problems). Host came in next morning with Proseco and pastries, awesome detail. The apt is well taken care of.
A little loud outside on weekends, if you have the window open, other wise no problem at all.
All and all a great place to stay. Also a great place to start a walk all over the city.
