It was very easy to check in and out of the location and conveniently located between two different rail stations so we had options depending on our day's travel plan. The studio is just big enough by western standards for 2 people and to move around the apartment comfortably and to store/access their luggage. Anymore than 2 people would be a tight squeeze.
The studio apartment is located on a quiet road off the main stretch so there was little noise disturbance at night, but was very close to many restaurants, convenience store, and bars.
Communication between Ohkubo and I were excellent. He was very responsive and provided very clear directions and information on the location and apartment appliances.
