Grazia’s place had everything I was looking for : a good location in Trastevere, a quiet place to sleep, and a desk with good wifi for working. It was exactly what I was looking for, not fancy but comfortable and effective :)
When I was there, the guests kept to themselves and the common kitchen area was often open.
Note: The listing said to contact the host for specific directions for check-in. I let them know I would arrive late, as instructed, but I didn’t receive any special instructions, so was a little worried I’d get to the address and not know my next step. But it turns out, everything was very well labeled and easy to find.
