In 4.5 months I visited Berlin 6 times and stayed at St Christopher's the majority of those visits. Each time we walked through the door the staff remembered us and tried to convince us to stay longer. Somebody please get me a job at this place. Everything is awesome.
Would go back for Neno alone. But there is no kitchen, it's literally a microwave due to croatian law! (Hence all the pasta in the free food section)
If you have an eccentric grandma, you'll feel right at home. It's like being at her house.
