The best things about this room are its location and communication with the hosts. The room is 15 minute walk from Termini train station and within walking distance from the historical center, Santa Maria Maggiore and San Giovanni in Laterano. Due to perfect communication on the part of the hosts, there were no problems with check-in.
One thing to take into account: the room faces a street, so even at nights it can be noisy. Other than that everything was ok.
