Having lived in Tokyo over 41 years, I knew Alt Stay would be conveniently located. What came as a surprise is how quiet the place is despite its proximity to entertainment and shopping.
My room — the smallest on offer — was clean and generously equipped, and large enough for one person living there for two weeks (or a couple staying up to maybe four nights). Its only shortcoming was its darkness since it’s in a semi-basement. If you’re travelling as a couple, I’d recommend paying up for one of the larger rooms, which I’ve been assured gets plenty of sunlight by someone who has stayed in one.
All considered, though, you’ll have a hard time finding better deal value-for-money in Tokyo lodging.
