I attended a congress at RAI Amsterdam. The place was very close by and I rented a bike and could get everywhere in town in 10-15 minutes. The area is nice with sweet cafes and small shops and a nice square. A good place if you just need a place to crash! Small though, so not a place where you stay in! Good communication with Ned all the way through. Will definitely recommend it for other people who attend congress or other things at RAI, and just need a place to sleep. The wifi worked problem free.
