Most of our hostels have a fridge and a microwave in common areas that will allow for simple food preparation and reheating, but no kitchen.
You should find a kettle there, but if it's gone missing (again!), you can always get hot water at the bar!
There is a Belushi's bar or a pub in every St Christopher's hostel where guests are entitled to discounts and/or daily hostel meals.
Only the Flying Pig Hostels in Amsterdam have a fully equipped public kitchen that opens after the hostel breakfast service.
