My partner and I (with our 1 year old) stayed here on the last night of our two week trip around Japan. We booked it as it looked perfect for what we needed and was in a good location both to get the airport and to explore a bit more for Tokyo.
The staff, check-in and communication were fantastic (they even kindly carried our bags up to the room as the stair were quite steep).
Super comfy bed and very well stocked apartment. Perfect of our last night in Tokyo stay. Thank you very much Aiko.
