Amstel House does a great job of making a stay in a hostel as pleasant as it can be. That being said, it's definitely still a hostel. The bunk beds creak and there's no guarantee the people you're sharing a room with will be remotely respectful, though three of my four nights were still reasonably good for sleep. The inner courtyards are bustling with very loud deliveries, and with no air conditioning in the summer that means everyone facing inward is going to need hefty ear plugs to sleep past 8am. The beds were unexpectedly very comfortable, having a sink in the room was a nice touch. The location is fine if you plan to explore during the daytime, but if you're in Berlin to check out the night life it's quite inconvenient to get back to after the trains stop running .
