The apartment is compact throughout but accommodated three of us with the use of the sofa-bed. Kitchen and toilet / shower room were small but do the job and, again, were spotless.
The building and location were quiet and ideally placed for the Colosseum and Forum and picking up the open top bus stores, walking to the Pantheon and Trevi Fountain was easy enough.
Juliano the building's manager was really helpful. Right across the road from the apartment (on the corner) was a wonderful, proper Italian restaurant but expect to queue and wait.
All in all, we were pleased.
