This apartment is in a perfect location for most of the key sights in Rome. We were able to walk to most places we wanted to see in 20-30 mins.
We found that we often preferred to come back to Trastevere to eat dinner, as the selection of restaurants was superior to anywhere else we looked.
The apartment is lovely, perfect for a family of four. There are numerous supermarkets around, as well as buses and taxis. We used the kitchen for breakfasts and lunches, and it was great for this purpose.
The only negative, which is probably over all of Rome, is that at night noise from outside and other apartments would wake us up. This is due to the courtyard designs of the buildings and the stone and tile construction. Next time, we would bring ear plugs for sleeping. This would not be unique to this flat. 100% recommend this flat, and we would definitely try to return here if we ever return to Rome.
