The Honigmond [German for honeymoon] hotels are my favorite hotels in Berlin. The furnishing is to a very high standard, lots of natural high quality materials which I personally always prefer, especially the hard wood floors. The Honigmond Garden Boutique Hotel gets extra points for the amazing, luscious inner courtyard garden & slightly more convenient location although they’re both very conveniently located within short walking distance from public transport incl. Berlin Central, fantastic specialty coffee shops & one of my main customers [important for my business travel]. With regard to business travel, like usual in boutique hotels there is a dearth of conveniently placed power outlets but you can make do. Also, no elevators. In my experience the rooms at the Honigmond Hotel are in a newer state than at HGBH but that might not be representative.
