Got 2 rooms for a total of 7 family members. The check-in process can be a bit frustrating as it's all done via an on-site iPad rather than through a human. Use the check-in code you receive via email to begin the process and then have the iPad take pictures of either the passports or Japanese residency cards of each individual. Once you do this, you get 1 code to enter the building and another code to enter your room. Unfortunately, I never received confirmation emails that contained the check-in codes for our 2 rooms, but luckily the phone in the lobby dials directly to the main office where an employee was able to help us check in.
The rooms themselves are not your typical hotel rooms. Indeed, the building was an apartment building. No TV (I brought a projector, so it wasn't a problem for us), but you got separate rooms for the toilet and bath, fridge/microwave/washer/kitchenette, and lots of amenities. Rooms are clean and very secure. Doesn't have much floor space, but what budget hotel in Japan does? Pricing is competitive when you consider amenities, but standard hotels may be cheaper/better for some.
Location is top-notch, a 2-minute walk from the Higashiyama metro station and within close proximity to Yasaka Shrine, Heian Shrine, and Kiyomizudera and the adjacent shopping streets to the south.
Cons are the absolutely abysmal Wi-Fi (luckily I have a Japanese phone number) and lack of outlets for charging. Recommend you bring an extension cord.
