This place was exactly what I expected- a great deal in a residential Tokyo neighborhood and an ideal place to work remotely for 3 weeks. My husband and I were able to work in separate rooms without too much disturbance (wifi was great). It was very conveniently located near the station as well. I knew it would be a bit of a ways from all of the hustle and bustle of the more touristy sites, but it was never too inconvenient. I met friends out in Shinjuku many times without issues. There are also plenty of food and restaurants nearby that are very affordable! It was awesome.
Additionally, the hosts were incredibly responsive and accommodating. Any time we had issues, they were quick to respond and very helpful. Keep in mind that the winter season can be very cold so having too many electronics on will trigger the circuit breaker. But it was all kind of part of the charm of living in Japan!
Highly recommend this place for living like a local and getting work done while traveling.
