Kanako was a great host from the start. She was prompt at answering all questions I had, easily available when I had to adjust my dates and to allowing us to have access to the spare key.
The apartment was exactly as described. On the smaller side but the floorplan made it work and was comfortable for 2 people along with 4 pieces of luggage. The location was close enough for an easy 10 minute walk and/or a quick and cheap (~7 yen) taxi ride from Shinjuku station.
Note that the building has no elevator and the apartment is on the 3rd floor (2 flights of stairs
Thank you for a wonderful stay.
