Kimie's apartment was very well managed, both communication and check-in/check-out were very straightforward and easy.
The location is about a 10-15 min walk from quite a few trains/subways, so quite convenient in that respect.
The internet was generally good most of the time, but had some connectivity issues from time to time. Overall very nice though.
The room was well equipped as shown and overall quite nice, but the bed sunk in the middle and was uncomfortable. I think this is probably because the bed frame was meant to have a traditional mattress and not something as thin as a futon mat. I ended up just putting the futon directly on the floor after a few nights of bad sleep since it was less painful. The only other issue were number of flies in the bathroom and the creaky bathtub, which weren't the end of the world, but still a little annoying.
In any case, despite the setbacks, Kimie's apartment was well worth it considering the price per night relative to other options in central Tokyo and I would recommend it to anyone on a budget who is interested. However, the bed was a dealbreaker for me, so I don't think I would personally stay again unless that was changed.
Regardless, thank you Kimie for your hospitality!
