Location is great - that's the main advantage.
We arrived around 8pm - at this time the reception is closed. We paid with cash to some man running a nearby restaurant, without any bill of sale (we got it the next day) and he gave us a key.
Room for 4 people (nr 25, last floor (3rd?), steep staircase, for wi-fi range go 1 floor down) - quite ok for hostel (no complains about the room). It's big enough to put 4 beds, table, 2 chairs and almost-without-shelves wardrobe.
But the bathroom, which is situated in the room (plus for that) - very poor. Water didn't run down in both sink and shower. It's usable, but needs renovation for sure.
To sup up, if you don't care about a condition of the place where you take shower, it's budget type, great located hostel. But I wouldn't recommend it for staying. There are other cheap hostels in the centre of Amsterdam, I hope they are better.
