The accommodation is a wonderful working spot and is perfect for 1-2 people. The wifi is really fast and wonderful for working from the location. The host has provided pretty everything you would need for long-term stay, but there is a whole bunch of convenient stores and a grocery store nearby if you need anything else.
The airbnb is a quick 5-10 min walk to the train station, and it only takes roughly 5 minutes to get into Shibuya and maybe roughly 15-20 min to get to Shinjuku.
Ranka was also extremely responsive and helpful in times of need!
