I spent 5 days with my girlfriend in Guido's appartment and it was great !
The flat is very clean, luminous and calm, in a very nice property with a garden.
It is very well squared, at 100m from the Trevi Fountain.
There is many shops and restaurants in the very street.
It is very central, so we can go everywhere by feet.
This is the perfect place for a few days in Roma !
I recommand.
