Marco has been a great host! :) He and his family welcomed me with open arms into their home, answered any questions I might have, and last but not least they granted me full privacy.
The room is indeed Nice and spacious and squeaky clean. This room is within their apartment, so I shared bathroom and kitchen with the hosts, No trouble whatsoever.
I did not utilize the options of a free Braziliansk Jiu Jitsu class or a ride in the Microlight Plane with Marco, but I recommend anyone who is staying for a longer duration than my two days to try it out ;)
The apartment is located quite a bit outside of the old city center, but I got to visit the sights(Trevi Fountain, Pantheon, Borgo St. Angelo, The Vatican etc) without problems, as the tram and bus connection is very good and gets you home safe and sound in the evenings.
