I stayed for 7 days at J STAY GUEST HOUSE 201号室. It is a small building with 2 rooms per floor. The room is very modern, clean and i slept very well there. In front of the House there are 2 Vending Machines for hot or cold drinks. Around the corner is a very good ramen restaurant. And there are a lot of sushi restaurants too. The Hibiya Line Underground Station Tsukiji H10 is the next subway station. (5 min walk) To Ginza Core you can also walk in round about 8 min. The staff is very helpfull and i wrote a lot of emails with the host. Thanks to Sayaka! The self check in and out was very easy with the post box. Hope to come again next year. Everything was perfect!
