Gemma's apartment was great; located close to the train station and some cool sites like the Colosseum. The apartment is one the top floor and has a lift, making it easy on travelers with backpacking gear. While Gemma couldn't be there for our arrival, she was responsive and helpful. The air conditioned apartment was ideal in the Roman heat, however the wifi was not working while we were there despite our efforts to reset it. While we alerted Gemma to the problem, she couldn't lend a hand due to other circumstances, which made it tough to check into flights, etc.
Luckily there's a pretty good cafe downstairs with wifi. It also has some damn good gelato, so if you're in an Internet pinch, grab a scoop or six and log in from there.
