The stay was very pleasant, and the host was always responsive. The biggest problem was the breaker was easy to flip, and unpredictable. Sometimes it would flip after several hours, and at least once it happened after we got home and flipped one light on (it was on for 10 seconds before everything went dark). This would cause us to lose power, and during the colder nights of our stay it was quite uncomfortable waiting for the apartment to heat back up. At one point it went out three times in one day, with the same usage as had been working for 4 days prior. Once we knew how to turn it back on, it was an extremely easy process but still inconvenient. Overall, the host was polite and extremely responsive to our messages, and the room was in a really good location for traveling around the Tokyo area, but the power going out was a big damper on the stay.
