1) I stayed for 6 days and 5 nights with breakfast, and there were only 3 fixed selection items everyday. However, I felt a bit bored on the third day. If it can be changed to buffet or semi-buffet is much better, there will be more choices.
2) The toothbrush provided by the hotel has a very hard brush head, and the enamel on the teeth will be brushed off even with the slightest force. The gums will also bleed. And the tooth paste is difficult to squeeze out. There is also a smell in the bathroom, which requires tape water for more than 10 minutes before it subsides.
3) The electric kettle only ha a small capacity and cannot be reheated continuously. If you want to have cup noodles as a late night snack, you cannot handle 1 large, or even 2 small portions at the same time.
Overall it's good.
Clean with convenient transportation. It takes 3-5 minutes to walk to the subway entrance, and 15-20 minutes to Tsukiji Market and Ginza.
