We loved Fadahouse and Dario was an excellent host and always got back to us quickly! It is light and clean and a joy to stay in. 4 of us stayed there for 2 nights and thoroughly enjoyed our stay. We used the 3 main beds and they were very comfortable. Dario went out of his way to check on something for us before we got there. When we arrived he helped orient us around the house and with directions no a map of Rome and he happily met us on time at the beginning and end of our stay. The vaulted ceilings were great! The street that it's on is nice and the windows keep out street noises very well. It's in a very safe feeling neighborhood with a few restaurants, a health food store, supermarket, and other establishments within a few blocks.
It is a walk or bus ride from the Roma Termini central railway station and there are very many buses available at nearby Piazza Fiume which helped us easily get around with the help of google maps for bus/subway lines.
Wifi/internet access was fast and good in most of the rooms except the big bedroom and kitchen where it faded, probably due to solid walls.
We'd definitely stay there again!
