The apartment was perfect for a couple to stay in Rome for 4-5 nights! It was really clean and even though it might be a tad small, it's fine if you're out and about all day.
The only thing I would recommend is to bring an eye-mask since there are windows that give into the hallway and the other tenants can turn it on at anytime, so the room can get bright in the middle of the night.
But other than that, everything was perfect!
