Katsuo’s place was as described. It’s a small apartment, but we didn’t plan on hanging out there, we just needed a place to sleep and shower. The location is awesome if you do the Mario Karting (which I highly recommend) it’s a 5 minute walk from Katsuo’s. Lots of little places to eat nearby, very tasty. Close Shinagawa station, we opted for a taxi, which was only 560 yen. It’s also a 1-2 minute walk from Shimbamba station which is a stop down from Shinagawa. Great location if you’re flying into Tokyo. Place was nice and tidy. Stairs are steep, so not great for those with physical limitations, but otherwise a nice place. The mattress is firm, which I like, but my wife thought it was too hard. Futons upstairs in the loft. Sleeps 4. Small kitchen, but we didn’t cook. Overall, great place.
