The place was bigger than I expected. Good space for a Tokyo apartment. I'd stayed in another Airbnb before and this one was much bigger and more comfortable, especially the shower. So that was a plus. (Though still small by regular standards.)
Great location, with easy access to shinjuku or Shibuya and harajuku. Close to Golden gai. Some might find staying in one of those areas more convenient, but I think this spot was more than fine and easy to get around. Access to both the brown fukutoshin line and the pink oedo line. Which are really convenient and can get you to where you want to go. Also a 12 minute walk to shin-okubo for green line (or just transfer at another stop).
Has an in unit washing machine, no dryer but hangdrying clothes was fine overnight.
Also, protip.. the "heater" noted in the instructions is a hot water heater for the shower. I found 50 degrees to be the right temp.
