Our time at the houseboat was great! Stevin and Jol were very nice and friendly. It's a houseboat, but the place was more than enough. You will find everything you'll need in it, coffee, milk, tea, towels, hairdryer etc. There is a kitchen in it too.
It is located near the central station and the inner city, about 10-20min when walking. Nevertheless it's quiet enough to find your sleep. There are also two bikes included. What else do you need? I highly appreciated my stay at Steven and Jol's place and I recommend it to the Airbnb community:) thanks again to both of you
