Tiberhaus was great. A great neighborhood and really close to the Testaccio Market, which is excellent! It is a bit of a walk to connect to public transportation, but if you are willing to wait for a bus, there is a stop right by. Very good value for the $$. Gianni had a guide for local places: Caffe, Restaurants, etc. which was great. The Air conditioning also worked well, which I definitely needed during unseasonably hot May week.
