The place itself is very nice and practical. The building not so much. The instructions to find it are a bit misleading, needs to be improved. Had to spend first night in a hotel as we could not find the apartment. He denied waving the first night fee. Sinichi is prompt in answering questions, but seems he does note understand english or uses online translator so communications are not easy as he seems to understand differently. Mind that apartment is in a 10th floor, we had an earthquake at 1 am one night and it is terrifying. 6 minutes walk to Gotanda Station both metro and JR, plenty of restaurants, minisupers and the like. We had a great time!
