We stayed at the apartement for 10 days and highly recommend it. It ist located in a very nice and quiet neighboorhood very close to the beautiful beach and not to far from the city center (aprox. 20 minutes with bikes). Nienke is a very caring and thoughtful host and makes sure everything is pleasant for the guests.
Guests should be aware that the apartement is one big room, but due to the way it is furnitured it did not bother us.
To conclude, this is a great affordable place to stay and we would choose Nienkes apartment again for our next visit of Den Haag!
