I must say I was very impressed with Germana's place. My wife and I only stayed for 1 night but we were impressed with both how clean the space was and the thoughtful amenities (cookies, a bottle of wine in the fridge, full stock of shampoo, conditioner, etc.). The location could not be more central in Trastevere while still being quiet enough at night. I wouldn't hesitate to book German's place if you're looking to stay in Rome.
