The room is large by US standards. By Dutch standards, it is enormous. There's a double bed, a couch that makes into a second bed (I slept on it; it's comfortable.) There is a big TV and WiFi. As advertised, we had our own toilet room, with shower.
Wouter is warm, welcoming, helpful, and glad to help. He encouraged us to use his kitchen, which meant we didn't have to buy breakfast out every day.
The room is not close to attractions. If that's important to you, pay the extra 200 to 300 Euros per day. It is close to the excellent Amsterdam public transportation, and close to our grandchildren.
