The location is great, lots of sushi places and near to Tsukiji Market. Close to Ginza so an easy walk to lots of shops and restaurants.
Everything was very comfortable and clean.
The hosts are communicative and arranged for early check in (paid, of course) because my flight was getting in early, which i really appreciated.
The online check in system and door code system works really well so you don't have to take a key with you whenever you leave, though you do have to take a note of your room door passcode.
I highly recommend ITH Tsukiji!
