My friend and I had a wonderful time in Rome! The apartment was conveniently located: walking distance to the coliseum and all the historical sites, as well as termini train station.
Check in was easy, even though we arrived late at night. Piera's son was waiting for us in the apartment and spent some time to explain to us everything and answer all the questions that we had. He also helped us carry our suitcases up the stairs.
For check out we had to leave the key in the apartment and close the door behind us. I love this option since we don't need to plan another meeting with the host and can leave the apartment as soon as we are ready.
The place looked exactly as described on the pictures. The bed was comfortable. This is all we really used the place for.
I recommend Piera's place to everyone visiting Rome for a holiday!
