Around a 10 to 15 minute walk from Shibuya station, some parts slightly uphill, and a little hard to find. I suggest to look it up on Google maps and save the location beforehand first. Even though it was around 10.30pm when I was making my way to the hotel, I didn't feel unsafe.
A helpful member of the hotel staff carried my luggage up (there is no elevator) to the 5th floor, the top floor, and explained to me the amenities and facilities provided. There is a railing that runs the width of the room where you lock your luggage with the lock they provide. Amenities provided are pretty awesome, like a toiletry bag containing a toothbrush, hairbrush, and sample-sized toiletries (for you to keep), and a yukata (which you leave behind). Communal bath is on the second floor, with a full-sized towel and face towel (to bring into the bath area, but not into the onsen!) provided there. A locker is also provided for you to keep your belongings. There is also a resting room on the second floor with two computers and tea available.
Bad thing is that the capsules aren't soundproof, so if you're a light sleeper, I would suggest you not to stay here. Even when neighbours closed the blinds to their capsule, you could hear it. Also, the Expedia offer is misleading, as it shows that a free nano-SIM card is provided, but in actual fact you only get the SIM card if you book through their website. Good first time experience overall.
