We absolutely loved the hidden house! We were 4 people travelling together and had no problem while our stay. Renee and her husband Maarten were very helpful throughout, answering all our questions in detail. The house is small, but every nook and corner has been very well utilized and you will not feel space crunch at all. And the guests have the option of using the house garden which is great. The location of the house is awesome, tram stations of line 3 and 4 at walking distance. A lot of cafes and eating places are also nearby.
All in all, a great experience.
