Location is great, in the heart of Trastevere. A lot of restaurants, places where to spend nice evening. Just in front of the entrance is nice pizzeria.
Apartment is big, clean and cosy.
Beds are big and comfortable.
In the kitchen you may find everything you might need (but not sure is you need to cook if you have so many restaurants in walking distance).
I would strongly recommended this place for your next Roman Holidays.
