The flat in Den Haag was absolutely amazing! My friends and me arrived late at night and followed the kind instructions of the owner (Surya). Everything was prepared to our arrival: sleeping places for 4 ppl (one big-size Ben in sleeping room , one bed for one person in separate room, and special extra-sleeping place-mattress which was also very comfortable). The flat was super clean, with big kitchen, washing machine and cosy terrace where we had coffee in the morning.
We travelled with car and didn't use the city transport , but have seen that right at the building is bus and train stations , many shops , and something like 15 minutes walking to the beach.
We enjoyed a lot the city , the country , and our rest time with friends in Surya's flat was just perfect! We highly recommend both the city and the stay point by Surya!
P.S.: One little recommendation from experience: the number of house is also the number of flat. So in case you don't see the number 80 at the entrance of the house , just enter steps inside and you'll find the number 80 as a number of flat.
