For anyone looking into this Airbnb, there are a few things of note:
1) It is a residential hotel, therefore look away if you're specifically in the market for an apartment!
2a) It is certainly a farther walk to Akihabara than advertised, more like 15 minutes walking and that's at a NYC pace! There are a fair share of subway stops, the closest being 8 minutes away, however.
2b) And there is a fair share of food options as well, we went to the ramen place the hotel had flyers for which was pretty good! There's also a convinence store less than 5 minutes away and a rather popular cafe on the nearest street corner.
3) This particular unit (503) is rather large for the hotel. It was very comfortable for me and my partner to spread out in terms of Tokyo space (and Japan in general!) It has a kitchenette with sink, hot top, microwave, and mini fridge. Can't discount this as it was very helpful to reduce costs!
4) Check in and out is extremely easy as long as you follow Masahiro's prompts fully!
Overall, I would stay here again. If you decide to stay here, take a walk around Ueno park. It's gorgeous, relatively close by, and a nice walk!
