A 7-10 minute walk from Nakano station, Aileen's space is beautiful! Fits comfortably for 4, although travelled with 3 only. Instructions given by the host was clear and concise - check in was a breeze. We stayed on the 4th floor, and thankfully there was a lift in the building! As the place might be in the midst of being cleaned, we could not check in earlier but Aileen let us know the location of coin lockers that we could use, which was the one at Nakano Sun Plaza right beside the train station. Place was spick and span, and more importantly, big enough to open our luggages and comfortable as this was our last accommodation before we had to depart Japan.
