Aileen's place was very clean and new, located in a quiet residential area, but still conveniently located close to Nakano station. There's an abundance of small restaurants, convenience stores and the popular OIOI department store with a grocery store in the basement floor. The entry and check-in is very smooth as it's all electronic so all you need to remember is the passcode instructions and no need to bring along a key. We also bumped into Aileen and her husband whom were very friendly and made sure to let us know we could contact them at anytime. In terms of amenities, the beds are very comfortable, shower is clean and convenient, and laundry is very easy to use. 100% would stay at Aileen's place again next time I visit Tokyo!
