I stayed here for the few days remaining of my trip. At first I was worried it'd be too far from central Tokyo, however I was wrong. It is very conveniently located to Shibuya and nearby Shinjuku area, so it was fine after all.
The size is as you'd expect for Tokyo at this price, so not much to comment.
The check in and out was very easy. However I didn't realise there were one flight of stairs to get the apartment, so heads up if you have large luggage like us.
Beds were decent, but I'd say not more than 2 people because there isn't really a common area - so it got pretty crowded with the 3 of us.
There was a strong smell in the loft? Not sure what it was can't say for sure positive or negative
