I was very pleased with Shizuka's Airbnb and would definitely stay there again. I stayed there for 3 weeks end of July and in August 2021 (including for self-quarantine due to the covid restrictions) and it had everything I could hope for: cleanness, hosts' responsiveness (!), good and reliable wifi (suitable for teleworking), convenience store at a 10 seconds walk (!) and little supermarket at 30 seconds walk, quiet surroundings and neighbours, towels, bedsheets, clear instructions on how to do the (self-) check-in and check-out etc, airconditioning, little balcony. The bed was comfortable (there is a mattress and an extra little mattress on top to make it very comfortable), I slept like a baby. There was also a disinfection spray available for free which was much appreciated, especially in these covid-times. The appartment is accessible via the elevator (or via the stairs) which was very convenient for my two heavy suitcases. The little table with 2 chairs are perfect for eating or working. While the interior is not super modern (it looks like on the pictures), I felt at home and found the price to be cost-effective. The Airbnb is close to the subway and at a +- 15min walk from the JR Shinjuku station. I recommend it for singles or couples alike.
