Place was convenient and very close to Okubo station after transferring to local rail line at Shinjuku station. Apartment sits over a produce store, close to convenient stores and you hear the usual noises from the city street. Noise is not bad for those used to city life. Place is very small and can be tight with only 2. More than that will likely be less comfortable. Due to small space, I would not recommend staying more than a few days. It was perfect for staying 1 night and still be within 1.5 hours to get to airport next morning.
