The owner was nice and helpful. We got there late (after 9:30pm) so she met us then. We didn't know there was a charge of 10 euros after 8:30pm, 20 euros after 10:30pm, 30 euros after 11:30pm, 50 euros after 12am. I didn't know the room is only serviced between 10-11am so we couldn't get fresh towels the second day. You have to let her know before 11am each day when you will be gone.
Also, for Americans, the lack of a toilet seat and lid are somethings that are difficult to adjust to. The room was clean. The area was nice and easy to get to the colosseum, restaurants, etc.
