I stayed at Sidney's place for 18+ days in January 2017.
I plan to stay with Sidney the next time I visit The Hague.
It was a large clean space with a comfortable beds, great bath, and a usable modern kitchen. I made good use of the washer and dryer in the apartment. This is on the fourth floor and there are stairs. I am 76 in good health and had no problems. The public transportation was excellent with an East/West tram stop across the street. I am from Tennessee, USA.
