I've stayed for a month here.
Location is perfect: close to the subway, bus and several grocery stores, as well as plenty of restaurants, bars, shopping malls, museums, cinema, and whatever you might need.
Ayaka san is very helpful and very responsive host, has been supporting me through entire stay and accepted some last minute requests in a friendly and welcoming manner.
The appartment is quiet spacious in comparison to other places. So you can comfortably accommodate your suitcases and other stuff.
The place has everything you might need for a lovely stay.
