I didn't get to meet Yumi but she was a very efficient host and very welcoming in answering questions and little requests. Her apartment is cozy and in the best part of Tokyo as everything is near! Food shops and restaurants are all a few steps away and I particularly loved the place right beside the building...extra bonus for their cute little weekend garage sale. Was able to buy cute little items for my nieces. Overall a great experience and would recommend to anyone. Will definitely stay here again. :)
