I had to change my booking dates twice and the host was very flexible with it, letting me change them with one day notice!
A room with a patio in a 3 person appartment in Rome.
Its normally not possible to use the kitchen and washing machine, but it can be discussed with the host or other residents.
Be careful if booking in a hot season, it doesnt have AC.
It does however have a fan.
The food provided was coffee, a bottle of juice and a bottle of water, as well as some cheap croissants and cookies.
The shower has seen better days but it works
