We were travelling to Amsterdam with four of my friends and we needed room for us with reasonable price. Fortunately we found 5-person private room from Amigo. We paid 500€ for 4 nights, which was bargain for us. The hostel was in very good spot, everything you need is in 100m radius (restaurants, coffeeshops, markets). And if you need to go the center, it only takes 15-20min by tram. When we arrived to hostel, we were surprised how steep the staircase were ( this place isn't fot old people or people with heavy luggage.) The check-in went smoothly and we got in to the room. The room was very small (9m2) had 2 bunkbeds and normal bed. There was sink, but no bathroom (there was one at the corridor). Even though the room was small, we only needed it for sleeping so it didn't bother us at all. The beds were surprisingly comfy.
So in summa summarum, I would recommend this hostel to young people who are travelling lightly and only need place for sleeping and storaging luggage.
