I liked Giada's place, very clean and big enough for three persons. Good connections to the center, bus stop only 2mins from the place and also Trastevere train station in 10min walk.
I would only suggest to Giada to improve the check-in process. Our flight was postponed for more then 6hrs due to Italian Air Control strike so we arrived around 3am even though it was planned to originally arrive around 21h.
Giada made good comment that she is not renting a hotel room but still many unplanned things can happen and more guest can be late. I appreciate that she was waiting for us the entire night but our arrival was already very stressful and the check-in experience also added huge pressure on me. I have been traveling lot and first time experiencing something like this.
As she has already implemented electronic cards system I would re comment to her to also invest in a Airbnb Lockbox or Smart lock Choices so that will reduce the stress on both sides.
All the best,
