Stayed for 6 nights, and it is a cosy place stocked with all the day-to-day items you would probably need, e.g. scissors, umbrellas, etc.
The beds are those fold out ones with wheels on them, so you need to be careful not to walk into those wheels in the first few nights. The mattress is quite thin, I didn't really mind it though.
The location is great! It's a quiet area, but a short 10 mins' walk will lead you to the main street area (and the sakurashimmachi station) packed with restaurants, supermarkets and shops. Restaurants during the week can open to quite late.
A further 10-15mins on the den-en-toshi line and you could be in Shibuya/Harajuku.
