Location is A++
The Good: Exactly like the photo. Very nice bed. Clean. Good AC. Excellent location. Quick and concise communications from the host. Close to station, supermarket, conveneince stores, excellent restaurants + cafes, coffee.... pretty much anything you need is 5 min away. Area has nice vibe. Very easy to get to Shibuya. Can even walk there along the green path.
Apartment is small, as stated, but 2 people could easily stay if you are only going to sleep there. Its about the size of an average business hotel. Enough room to lay one med size suitcase open on the floor. With all the close amenities, thats pretty easy to do. I dont think it works for 2 people if one needs to work, or one/both will spend a lot of time inside.
Caution: Street noise is very loud. I heard emergency vehicles late into every night. In addition zooming cars, trucks, mopeds, motorbikes etc were ever present. Light sleepers beware.
