We really liked staying at this air bnb and I would recommend it. We especially liked the location. It was in Korea-Town with lots of different Korean food, cosmetic stores, side stalls, supermarkets and K-pop. (Don Quijote was just down the street)
It's on the Yamanote line which is also really convenient.
The communication with our host was quick and direct with a user manual for how to find the place.
The host left us a wifi dongle which was also so helpful. I would recommend hiring one from the Airport as well if you will need more than one.
The washing machine inside the apartment was so helpful and there was also a laundromat just 1 min away.
Keep in mind that the apartment is very small but has everything you need. There is also a bathtub and comfy bed :)
My partner and I highly recommend this place!!!
