The flat is really lovely and perfect if you want to be absolutely central BUT you want to have peace and quiet for a good night's sleep (on a very comfortable bed).
Federico's welcome was warm and extremely helpful, not only did he provide an excellent description of how the flat 'works', he provided a map where he even pointed out places to get gluten free food which is a dream-come-true for a travelling celiac. Bravo Federico and mille grazie! I recommend this flat very much.
