Sergio place is perfect.It is under valentin hill, so it is quite walkable to aventin,palatin and few bus stops to colosseum.Area is occupied by local italians.For a such a price is one of the best location, which I saw.Sergio is very friendly and room is clean and comfortable.Window leads to the quiet area.Even in the hot summer he has small ventilator and thanks to it place is not so hot and pleasant.It is not always like that in Romans appartements.
