The period I spent in Nina and Niels house was really pleasant, they are so friendly and available to give you lots of information about the city and the places to visit. The bedroom is big, bright and with a really beautiful furniture.
The area around the city is really nice, with a lot of small cafes and place to eat.
Near the house you have several buses, and 10 min walking a metro station, so you can easily move around the city.
Strongly recommend!
