I came to stay for a conference at the Amsterdam RAI (there is no better location than this place - 8 minute walk).
Ned was super accomodating with both arrival and leaving. He was helpful with places to go.
Everything you need is just around the corner - stores, coffee shops, tram, bike rental, supermarket, parks.
The room is a small room, best suited for a single person, but also accomodating a couple with a bit of a tight squeeze. There is a hot plate to cook and some dishes, and a kettle for hot drinks.
Enjoy the place.
