We really had a relaxing time in Gabrielle's apartment. Even though it was always very hot outside (in June), it was always comfortably cool in the flat, we didn't even need the air con. The bed is very comfy and the terraces, especially the view from the roof top, are really beautiful. (Make sure to bring enough anti-mosquito spray with you though, they were really annoying.)
Gabrielle is a great and friendly host who quickly responded to our questions, helped us with recommendations and made sure we had everything we needed. She also provided some snacks, juice, milk and coffee and even bought us new coffee when we ran out of it.
You can explore rome and the vatican very easily with the public transport (buses and metro are a few minutes walk away).
All in all, we had a great stay.
Thank you Gabrielle!
