The appartment is very cute, the bed is comfortable and we were warmly hosted by a man who explained us the history of the city, the things he likes to do and he agreed to see us on sunday if we wanted to visit some monuments together.
The shower is small and if you are very tall, be careful with your head, but it's still very beautiful and in the very heart of Roma (5min far from the Trevi Fontaine)
We had some problems with our taxi, and our host were very helpfull on it. thanks a lot !
