The first night I ever spent in Europe was at the Old Nickle hotel in Amsterdam. Let me sum this up by saying if I return to Amsterdam, I will be staying at Old Nickle, and I always recommend it to those on their way.

The rooms are located above a small and quaint pub that is clearly only visited by the locals. This initially really turned me off for fear of loud, sleepless, nights. But that was never the case. The locals were always nice and the bartender/owner helped us out of several travel pofaws we found ourselves enthralled.
We stayed in a room with 3 beds. The beds were incredibly comfortable. Honestly cannot stress that point enough. They were amazing. Maybe that is the hangover effect of a sleepless jet plane, but I stand by my review.
The only down side to be prepared for when staying here, you will be sharing the bathroom with the other bedrooms on the floor, as in true hostel form. Lucky for us, noone else was on our floor! So all those post pub crawl nights of consequences were not an inconvience to anyone but ourselves.
