Franziska's place was just as in the photos; light, modern, spacious with lots of stylish touches. I stayed with some friends but was working during the days and there was plenty of space to work with lots of sunlight which suited me well. The beds are both large and very comfortable and the shutters block out all the light for sleeping. It's also surprisingly quiet considering it's so well located in Trastevere.
The location itself is fantastic, right in the heart of Trastevere, near lots of incredible restaurants and bars and a beautiful walk to the historic centre of Rome.
Check-in was also incredibly easy.
Overall I can highly recommend Franziska's place.
