My girlfriend and I stayed here for the last leg of our Japan trip.
It was a pretty relaxing stay and I definitely enjoyed the extra space + style that the room had compared to some of the hotels we had been staying at.
I think that the area is pretty decent - I've stayed in the area multiple times so I knew what I was getting into. It's not exactly central Tokyo but it's super easy to get around from the trains in the area. There's also some pretty good food.
Check-in was super simple and the host was responsive and did their best to accommodate us in every way.
The only issues I had were very small. One was that footsteps of the guests in upstairs rooms could be heard if they walked too heavily. Not a huge problem for me and the host actually provided earplugs by the bed incase you needed it.
I'd probably stay here again next time I'm in Tokyo :)
