It is a great apartment and the elevator to the 5th floor works well and is quick. As others have said it is the smallest elevator I have ever seen. Two people, or one person and one large bag is the max it will hold.
The noise from the street was loud on a couple of the nights we were there with very loud voices from after bar patrons going on for long periods.
Other than those two issues, the flat is in a great location, the bed is very comfortable and it was nice to have the balcony. Overall we really enjoyed our stay at Stepanie's place and would recommend it.
