The little house in the Zen Garden is absolutely unique, as well as the hosts, Annamaria and Guglielmo. The whole place is perfect to relax, in the Zen space, after running around Rome. The breakfast is a very nice surprise and tasty. Although the apartment is not in the central area of Trastevere, is is pretty close (15 min walk), restaurants around are top (and with good prices - for Italians and lucky people), and you may use the train just around the corner. All this, and the price is also very nice. A great choice.
