Naf's flat is very nice and clean with a stylish kitchen :-)
The room is small, but has everything one needs - a comfortable bed and a desk.
It's situated in a quiet area which is nevertheless close to the city centre - only a busride away (you could also walk or -even better- use a bike).
Naf herself is a person who made me feel welcome even before I arrived - she's easy to talk to (also written correspondance), has some good tips when it comes to e.g. eating out and made my stay enjoyable.
Definitely a place I'd go to again :-)
