I had an excellent stay with Matthijs and Francina. They were very friendly and gave great advise on how to see the city. They were also extremely easy to contact.
The room was simply decorated and very clean. The best part about staying here was the outstanding location! The building is in the very heart of the city, meaning basically everything is within quick walking distance or can be accessed by a short street car ride. Furthermore, the building is just (maybe 1 or 2 streets) outside the noisy nightlife part of town so there was no problem sleeping.
I can highly recommend staying with Matthijs and Francina.
