We had 4 wonderful days in Geert-Jans apartement. It was super cozy and it has everything you need.
We brought the travelling bed for our 2 year old daughter and she could sleep in an extra room.
Everything is reachable by foot, which is awesome. Less than one Minute To the beach and even with bad weather, the apartement is comfy to spend an afternoon inside.
We can only recommend this Apartment and Geert-Jan as host.
