The Shelter Jordan is one of two Christian-run hostels in Amsterdam - the other one is in the Red Light district. The website for them is

I stayed at the Shelter Jordan for two nights. Cross the bridge by the Westerkerk, and turn into Prisengracht. Bloemstraat is your first street on the left. The Anne Frank House is opposite, on the other side of the canal. Rozengracht is behind Bloemstraat, a main street with a laundry, takeaways, coffeeshops etc, though I found it a bit seedy at its upper end.
While the hostel was Christian-run, I did not find it too heavy handed. Guests are invited to bible studies, but they are purely optional. Dorms are single sex and quite large. I stayed in a 22 bedded partioned dorm. Lockers are provided. There is a patio area, and a cafe. Breakfast is either hot or cold, but it is not buffet-style. The hostel has a good selection of communal areas, including a patio, lounge and cafe area.
The hostel was very friendly and welcoming, and clean. The staff are mainly American.
The only gripe was that showers were tiny, and the cubicles had nowhere for clothes, towels etc. This is awkward if you are trying to keep your towel dry, and have a set of clothes on you. You can hang stuff on the door, but they risk getting very wet. There were queues for them in the morning. Also, luggage lockers were not really big enough for backpacks.
For 14 euros a night, this as as cheap as accommodation in Amsterdam gets. It would not be suitable for couples looking for a romantic time or all night clubbers (curfew is 2am and dorms close at 10.30 am for cleaning), but for the average budget traveller wanting secure, clean and centrally located accommodation for a low cost, this is to be recommended.
