Together with a boyfriend, we stayed at Arjen & Nathalie's exceptional apartment for 1 night during 1-week bike travel around South Holland in April'17. The place was very nice, clean, full of sunlight and had an excellent view of the balcony, located 15 minutes by bike from the city center. It is situated in a historical building, so the stairs are steep like almost anywhere in the Netherlands and Nathalie kindly let us store our two bikes in her own apartment, which is on the ground floor, for the night. Communication with the host was fast and easy, we got helpful advice about places to visit in Rotterdam.
Hope to be back again sometime soon!
