The communication has been amazing. Quick responses to our concerns before our trip took place. We had 6 adults and a 18 month child. May be a little on the small side with that many people, but we never felt cramped during our stay.
The house manual provided detailed instructions on how to get to the place. Even though we arrived around 11pm local time, the place was easy to find. The airbnb is conveniently located near the Takadanobaba station which has JR lines and Tokyo metro lines. It is about a 10 minute walk. There are several 7-11s stores nearby which allows you to grab a quick bite. There is a grocery store nearby, should you plan to cook during your stay.
There are two restrooms. One downstairs and one upstairs. Restroom downstairs is in the style of a wet room (A wet room is essentially a bathroom with an open shower (or one that is behind some type of wall with a shower floor that is flush with the rest of the bathroom.) The shower pressure downstairs is amazing and the bathtub is amazing to relax in. The bidet toilet is separated from the shower and bathtub. Shampoo/body wash/ and conditioner is provided. The washer (washer only no dryer) was nice to have. There were plenty of hangers to use to dry your clothes out on the upstairs balcony.
The house has wifi and no issues with that. Worked with no lag or glitches. The pocket wifi was an nice plus. It allowed us to use google maps and text each other. Keep in mind we also had our own pocket wifi in fear of the tenant's pocket wifi data usage may have met its limit from previous usages. But no issues with that during our stay. The TV has an amazon firestick.
Nice little touches provided by the host were appreciated. There was a Japanese language book we took during our trips, and there were books for speakers of various language. (french, etc.)
Many restaurants nearby, the options are endless. Two drink vending machines are available on the main road.
Overall a great stay with an awesome location. Would not hesitate to stay again.
