Sei made my first experience with Airbnb and Japan amazing. She was able to answer all my questions promptly and provided us with the most detailed, with pictures, on how to get to her location. The wifi in the apartment was great but the portable wifi was a tad sluggish and the battery did run out quite fast. However, we had a portable charger so it was not a big deal. This listing does state it is for 5 ppl but in reality I would not push it past 4. We had an incident where something broke down on us and her first concern was on our well being of our group. She came down immediately to assess the situation and had a solution in no time. Next time I go to Japan I will not hesitate to stay at Sei's location :)
