The view from the apartment was absolutely stunning, and the apartment itself was well furnished and comfortable. The tower is about ten minutes' walk from the centre of The Hague.
The information pack provided on booking was very useful, as it answered most of our questions about the apartment. Note that the Hague Tower is very close to Den Haag HS train station, but about 15 minutes from Centraal station!
The apartment felt a little spartan, and it would have been nice if it had felt a bit more "lived in" - e.g. soap had been provided in the bathrooms or coffee was left in the flat - but it was still a very comfortable experience in an amazing location.
