We got really late to the place and Chiara had a person waiting for us even tho we were 1 hour later there than we agreed. The place was even better than it was on the pictures and had anything you need for a short visit. Only thing was that there was to fault was that there was no proper blankets (there was blankets but no sheets to go with them),
I imagine it is fine during warmer times, but myself I prefer a proper blanket always and not just a sheet. Trastevere is a nice area and 15min walk away from the touristy stuff. I recommend the appartment and I would come again for sure :)
