The Flying Pig Uptown is one of the better hostels in Amsterdam, conveniently situated beside the Vondelpark and the Leidseplein (restaurants, bars, nightlife, historic sites, Rijksmuseum) only 10 minutes away by tram and or bus from Central Station. The hostel is very well taken care off by the friendly staff, clean beds, clean showers and toilets. Lockers are provided and under the beds you will also have a locker that you may lock with a padlock.
The hostel has a nice bar and a smoking room which is always cozy. Pub crawls and other events are organized by the staff as well, I really recommend this.
Tram 1 and 2, bus 170 and 172 go directly to the Leidseplein from Central Station and from there it is only a five minute walk to the hostel.
