A group of 18 of us stayed in the Grand Hostel in Berlin for New Year. The staff were really friendly, helping us find out about tours and giving directions to various clubs etc. The bar is amazing, it feels like you are in a beautiful hotel library with amazing gin and tonics and a great atmosphere. The beds are comfy, bathrooms clean and plentiful. Really good transport links and v easy to get to from the airport.
All in all I would recommend this hostel to anyone, and will likely be visiting again in the summer!
Thanks to all of the staff for a great trip.
