I had a comfortable but brief stay at Aiko's place. Although it looks like an apartment on the inside, I did receive hotel service when I was checking in and out. This unit was on the third floor and there are only stairs available, which presented a problem for my party as we all had a heavy luggage. A staff member brought out our luggage up and down the stairs even though we insisted we were okay. That is true omotenashi. Beds were pretty comfortable. The place was walkable from Uguisudani station - take the North exit for the fastest route, take the South exit if you have heavy luggage - literally a straight walk for 12-15 minutes. Bathroom was on the smaller side even for Tokyo standards but I was able to enjoy a nice shower and bath regardless.
All in all, I had a great stay and Aiko is a fantastic host. I would happily stay here again
