Self-appointed as the "most eastern" of the DDR-Designed hostels, this fun and well-conceived hostel offers time travel back into pre-Wende Berlin. Found in an unassuming concrete-block-style building typical of Soviet architecture, it's a great primer for anyone who wants to know what "ostalgia" (nostalgia for the DDR) looks like in practice. The "Ferienwohnung" (holiday apartment) is a masterclass: a true simulation of an living room east of the Wall, perfect for families who want a history lesson outfitted with all the modern comforts.
