We spent 3 nights in Amsterdam in Gordon and Amy's Yellow Room and were very happy with our stay.
The place was immaculate, the included breakfast was very generous (and delicious) and it is in an amazing location. WiFi worked a treat also.
The Yellow Room was easy to get to from Central Station and has great food at coffee at your doorstep. With a supermarket virtually across the road.
Gordon was a pleasure to deal with and kept both our room, and the shared bathroom/toilet immaculate.
Absolute pleasure staying here and would absolutely recommend it to anyone.
