Had a wonderful view of the Trevi Fountain from the end of the apartment building's hallway! VERY centrally located to lots of attractions and nightlife. Due to that, it was a bit noisy at night - we kept hearing whistles coming from the Trevi fountain area while trying to nap. But pretty minimal bother.
Giulia has clearly put a lot of thought and effort into making her space attractive and comfortable. The bedding was so fluffy and amazing! And the decorations are even cuter and cozier than in the photos. The shower is very small, but water temperature was good. The apartment is also very small so there isn't a lot of room to spread out, but it is very cozy.
We never actually met Giulia - she has an automatic check-in system so she can buzz you in remotely. Good for flexibility, but it would have been nice to meet her.
A note: Checkout time is very strict if she has someone staying the next day. We were supposed to check out by 11 a.m. We packed in the morning and ran out for coffee - when we arrived back to the apartment at 11:05 a.m. (our fault, clearly) someone was already in there cleaning and our bags were out in the hall.
I would recommend this place if you want to be in the middle of everything!
