Apartment was a great place to stay for a 10 day business trip to Japan. Much more space that a standard hotel room and very convenient to restaurants, convenience stores, etc. The Ningyocho area was walking distance to all of our meetings in Nihonbashi, but far enough away to still feel like a neighbourhood and not like an office park.
Hosts provided full and clear instructions that made getting to and accessing the apartment easy. And were super responsive when my jet lagged brain asked a dumb question that was clearly covered by the instructions.
