The apartment is in a great location, close to the colosseum and a reasonable walk from the Manzoni metro station (if pulling your luggage, make sure to walk to Via Merluna which is much smoother than the first unmarked street which has poor sidewalks and a cobblestone street). There are numerous bus stops nearby and we learned to take the ones that drop us off at the top of the hill so we could walk downhill to the apartment. After walking 8-9 miles every day the very moderate hill from the colosseum felt much steeper at the end of the day! It isn't steep at all, we were just tired after all the exploring. The apartment is close to the colosseum, Roman Forum, Circus Massimo, Vittorio Emmanuele Monument and more. You will do a lot of walking in Rome so bring good tennis shoes.
There are about 5 steps you have to go up to enter the apartment. The storage in the apartment is excellent. There is a dresser with 3 or 4 drawers as well as a large storage unit/closet with 4 drawers. The apartment was very comfortable for 2 people. The wifi worked very well. Check-in was very easy (self check-in). Communication with the host was good and we had no issues at all.
There is a cafe just out the door and to the right which had very good pastries for breakfast. We do NOT recommend Pizza Rustica which is down the street towards the colosseum.
