This unit is truly a gem! I stayed here for over a month while looking for an apartment in Tokyo, and it was a perfect home base.
The unit itself is very clean and well-made, even more so than I expected. The interiors feels modern, not luxurious but with a solid build and sensible lay-out. I stayed here for a month, and there were enough supplies (cleaning, bathing, etc) to last the entire month. Of course I had to go to the super market for food and condiments, but everything in terms of cooking utencils/plates were there. One tip, if you want fresh coffee, you can pick up the individually packed drip coffee packs as the market, and use the hot water kettle to make your cup of joe. The bed was comfortable, and you get a good amount of sunlight as well. I took many video calls during my stay, casual interviews over Zoom or video calls with family, and the wifi worked fine throughout for this as well as streaming Netflix on HD.
The unit is on the third floor so you have a sense of privacy as well as a bit of a view (you can see the Tokyo Metropolitan Bldg from the balcony). The aforementioned super market is just a few minutes away, which made it incredibly convenient to go purchase groceries and supplies. There are plenty of restaurants nearby as well. The train station is just 6-7min away, and it's Marunouchi line which is super convenient. I think even the locals would find this place to be very convenient.
The mgmt company has been very responsive and flexible, they gave me tips around garbage collection as I was staying for a longer period. I also extended the stay by a few days, and this process went smoothly.
The quality of Airbnbs anywhere can vary, and you don't want to reserve a spot for a month only to find out that it has some serious deficiencies. That is certainly not the case here, I can fully recommend this location if you're looking for a home base in Tokyo for weeks or even months.
