The flat is charmingly decorated and has modern equipment. Everything was clean and tidy, and the Check-in was fast and easy. Technically there is a 2nd expandable bed as stated, but we slept on the big bed seen in the pictured, where two persons fit. There are plenty super/mini markets nearby and you even can see the top of the St. Peter's Basilica from the window!
We had a great time in Rome and this place, Justyna seemed like a friendly person and also speaks basic English :)
