Overall, it was a nice stay for 2 nights at do-c gotanda considering the price in Tokyo. 3 min walk from Gotanda JR Station, having a wide shower & sauna facilities plus complimentary amenities.
However, sound-proof appliances should be installed for the guests to be able to enjoy their nights. Plus, I was struggling with finding out the accommodation when check-in, as it doesn't have a big banner showing the entrance. Inside the capsule room, I felt a bit stuffy, when closing the curtain, due to lack of ventilator & aircon in each capsule room.
