Don't be afraid by Sharon's really unfair comment. I am 5'9" and never hit anything in Kristel's apartment (and never had to be careful either), and the walkway to the unit was not so dark.
My girlfriend and I had a great time in the apartment. Everything was nice, clean, practical and the bed comfortable and even though we didn't meet Kristel, she was very nice and available.
The flat is located about 12 min by foot away from a subway station that leads you to the city center, perfect !
