Ruben's place is everything that you want and more. I'm never sure what to believe with location comments but his place is walking distance from everything, and there is a tram that gets you to central Amsterdam quicker or towards the airport just two minutes away by foot. The room is very big and has a large table for work and 3 or 4 very comfortable chairs. Balcony and garden also beautiful and the bathroom is large, clean with a good shower! There is tea, a hair dryer and other useful amenities. Agree on all of the nice bed comments - it's huge and very comfy! Ruben is super quick to respond to messages and is happy to help you out with anything. Highly recommended. Explore the area too, reminds me of east London.
