We were 3 adults who loved staying in the treehouse! It was in a convenient location, surrounded by good and varied food options. The small touches like decorations, Tokyo guides, local recommendations, games and the balcony were great too. As it is on the corner of a main street and above a restaurant it did get noisy from time to time and the loft/third bed was a little uncomfortable as it was hard to sleep on but all was fine for 3 nights. We highly recommend this place for short term stays for 3 people or longer stays for 2 people. I’ll be saving it as a favourite for when I return to Tokyo.
