Alessia is a wonderful host. The apartment is in a quiet residential area that is very close to supermarkets, and restaurants, plus outdoor mall, transportation, and easily walkable to Vatican City.
The apartment is large and very comfortable. The value is excellent. I did not use heat or A/C so I cannot comment on HVAC functionality.
Pros: Great host. Warm and comfortable apartment, feels like home. Location. Quiet at night. Adequate kitchen. Good bathrooms.
Cons: Internet upload speeds are .2kbs / sec. download speed is 9 mbs.
