We had a wonderful four night stay at Guido's apartment...everything we needed was there and it was the perfect base from which to explore Rome. The location is away from the crowds, very quiet at night for sleeping and set up high in beautiful green garden setting. The restaurants and bars of Trastevere are only a few minutes walk and there is a bakery and shop close by. The cafe at the top of the stairs makes good strong coffee (very important to us from Melbourne, Australia). The main bedroom had a very comfortable bed and the foldout couch bed was fine for our daughter. Everything I the apartment worked fine.
Thanks Guido also for the restaurant recommendations and the lovely bottle of Chianti when we arrived. Ciao!
