The flat is situated in the heart of Trastevere and is really spacious, it has two lovely terraces with really great views of Rome. We went as a group and had plenty of room to be comfortable. It doesn't get too noisy at night if you shut the windows and the flat has AC which keeps the rooms cool.
The only downsides are the wifi (which you can't connect to in most of the flat). We also struggled as we only had one set of keys. The keys are needed to keep the lights on when you're in, but it means whoever stays in the flat needs to keep the keys anyway.
