Kaen's place was clean, efficient and most of all in a GREAT location. We loved the Shin-Okubo area and it's in easy walking distance from the Shinjuku area and station. There's also the Okubo station very close to the airbnb which we utilized to get around the city quite often. This place was the perfect size for us and we enjoyed staying here. The only problem we had was the fact that there are neighbors above and to the side and someone would often walk around with what sounded like high heels on for HOURS and sometimes very late into the evening (about midnight). It was so loud and irritating unfortunately. We understand that this is something that is unavoidable but it is worth mentioning for those who are sound sensitive. That was our only issue with the apartment but everything else was great.
