Rosa is one of the best hosts I've ever had, she was very kind and helpful. I got to eat some of her cooking and it was delicious!
The location is great too, 5 minute walk from Roma Termini so it's stress free getting here after arriving in Rome. Considering the location, the price is fantastic. You can walk towards the station and get some touristy food or you can head the opposite direction and get some more local-directed food.
It's also right next to a metro station, you can hop on the metro and get downtown, or to Vatican City, it couldn't be more convenient.
If you like walking it's a pretty comfortable 20-ish minute walk to the sightseeing area of Rome as well.
Next time I come to Rome I would definitely book this place again. Surrounded by great food, fantastic access to transportation, awesome host, and great value.
