Location is quite far from Interlaken Ost. 15 mins by walk and 3 mins by bus (no 102). Bus come every hour so you need to plan when you will leave hostel for each day. Obviously that this hostel is very popular for Korean teenagers (80% of guest) when I stay at that time (22-24 May). Even hostel provide large kitchen but it's not enough for guests. Because some group didn't share the space for cooking so other groups have to wait for a long time. After cooking, many guests didn't clean properly. I fell sorry for hostel's cleaner. This problem is not hostel's fault, it's a common sense when everyone using shared Kitchen. So I would like to give this information to prepare yourself when you plan to cook here.
Staff is willing to help and answer your question. Hostel'll give some internal coins which you can use for free coffee or washing your cloths. All things are pretty good for our group except cooking time.
