Just one word to describe it: spectacular! was one of the 1st I found but wasn't available. Then the opportunity came to rent #771 for a couple of days prior to moving to our friend's place in Gouda.
The view is simply amazing, the apartment is also 1st class and with good connections to most important trains. I was very familiar with the area (having lived in The Hague for 5 years) but even so I think you can't get wrong in reaching most places in The Hague from the Haagse Toren.
We also had the pleasure of meeting Elwin the first day when he personally came to see that the TV system was working properly. In the end we wanted to stay a day longer but unfortunately it was already booked. Hopefullly for our last night in The Netherlands as it has good straight connection to Amsterdam airport.
The washing machine AND dryer were also a nice life saver as we were staying 3 weeks in Europe. The apartment was also very well equiped and the view made it almost impossible to take leave from the apartment.
