We enjoyed our stay at Flavia’s apartment.
The location is very central - 5 minutes from the colosseum and close to many restaurants and stores.
The apartment itself is comfortable, very well kept and equipped with everything you many need. Big bedrooms and bathrooms, washing machine, well equipped kitchen, hair dryers, detergents, soap, tea, coffee, sugar and other basics.
Keep in mind that this is central Rome and the buildings are old. That said this apartment is modern with all amenities
There are a few steps before u get to the small elevator.
As mentioned by others there is some street noise in one of the bedrooms but you are in central Rome! It is to be expected just like if you were in NYC or London City.
The hosts are very responsive - they kept in touch before and through out our stay, Fabio met us at the apartment and made recommendations about where to eat, helped with taxi booking etc.
We would absolutely book this apartment again.
