My husband and I had a nice stay at Gael's guest house over the Easter holiday. Gael was very responsive to inquiries prior to our arrival, and very friendly and accommodating once we checked in. Housekeeping was also an added benefit compared to some private home Airbnbs.
The unit is just as pictured; clean and functional. The floors are all cement so it felt a bit cold, but slippers and robes were provided, which was a nice touch. The wifi was pretty week and inconsistent, which I imagine is due to the cement floors and walls.
The location was great, and we were able to walk pretty much everywhere we wanted to go, and it was no problem to catch a bus or the metro nearby.
Overall, I'd say this is a good value for a basic stay in Rome.
