Bunk hotel is recommendable for budget travelers. Considering you are in Amsterdam, their price is way better the than a 3star hotel with small room.
Facility:
1. they have nice & quiet library
2. Awesome restau and bar(a bit pricey)
3. Nice chill area
4. luggage storage(they charge 8euro for 24hrs)
5. Toilet: you will never believe that the toilet and shower room is clean considering this is a shared area.
6. The towels are always fresh and refilled.
7. More to mention
Location: it is in the noord area so from the central you need to take a metro which is one stop(pay for one hour ticket = 3ish euro or you can go for a day pass for 8ish euro). From noord station to hotel you need to walk for about 8mins on average speed.
There is a supermarket nearby, approx 5mins walk from the hotel.
Safety: 100%. All rooms are accessible with card only. They provide you a small storage under the bed which also accessible with your assigned card.
During my stay my mates are all aware and quiet. We respect each other relaxing moment.
This hotel is highly recommended. Definitely will checkin again.
