We had a great time staying with Malo and Maarten. They were both so helpful and accommodating. They even allowed us to use two of their personal bikes when the four of us wanted to do a ride to Haarlem (I believe there were technically only 2 bikes offered for our use). They were great to recommend different biking routes and restaurants as well.
The apartment was exactly like it was in the photos. Nicely decorated with personal touches and many helpful travel books/guides. Really a nice space. Well kept up and very clean.
The breakfast they provided was much appreciated and we enjoyed it (yogurt, granola, bread, cheese, meat, juice, tea...).
There were three adults in our group and while I usually don't find "pull outs" comfortable, theirs was comfortable and I slept very well.
There was a small garden and outdoor seating area as well.
While the bathroom is small, it is functional and a good use of the small space. One tip is to only use the handheld wand while showering instead of the showerhead on the ceiling. By doing so, you will prevent the floor in the rest of the bathroom area from becoming wet from the shower.
