Fantastic location and fantastic host!
Lovely Trastevere is right in the heart of the best part of lively Trastevere, yet on a quiet street a block away from all the noise of the nightlife, so very peaceful. Great restaurants abound, and it's very close to the Ponte Sisto bridge, so the heart of Rome is a pleasant 15 minute walk away (Campo di Fiori, Piazza Navona, Pantheon)
