I stayed at Arthur's place for 3 nights and the experience was absolutely perfect in all aspects:
The flat was very, very well maintained and clean. The design was look after in every details.
Arthur and his friend Rachid have been very welcoming and responsive to every need.
The apartment is located on a very quiet square with plenty of trendy cafés , bars and restaurants.
What more to be said ?
I would definitely return to this address when in The Hague and would highly recommend it to friends.
