We did appreciate to stay in this great flat. It is very confortable, clear, large volume and very nice decoration. The building and the district are very quiet. Testaccio is a nice area close to Trestavere and the Colise. Bus and metro are easy to take if necessary. As we wanted to be close to the center but avoid to be in a touristic area, it was just perfect for us. The cherry on the cake : Sonia and her sister were very nice and helpful.
