Carla’s place is lovely, spacious and bright near the top floor of an elevator building. I stayed for 1 week during summer and the A/C was great as well as the washing machine. The location is a quieter part of Trastevere, a bit further from the city center but there is a bus stop just outside the building. I found myself taking Tier/Lime bikes around more often however, because the buses were often delayed.
I was working remotely and took many Zoom calls. The wifi was sometimes a bit delayed but overall it was fine.
Carla herself was very helpful and communicative as well. Highly recommend!
