the space is so cute and perfect for one person. (it might be cramped for two people, especially if you're tall).
it's slightly difficult to find if you're unfamiliar with the neighborhood. the walls might feel thin if the neighbors are noisy. (these are all very common qualities among apartments in tokyo).
the space itself is impeccably clean and well designed. the wi-fi is built-in and not a pocket wi-fi; so come prepared with your own wi-fi if youre visiting from out of the country.
