The best hostel in Amsterdam, very clean and warm. Stuff is very pleasant, actually they are owners and they are always near to help you with everything you need. They provide you with a city map and very useful inside tips.
It really felt like home.
Also, you can help yourself with water and beer or juice on a very low price. You can buy even an umbrella at the hostel.
Breakfast is very good considering that its just a hostel.
