Overall my friends and I recommend Tommy’s place.
Location : if you don’t mind a bit far from Tokyo downtown, tommy’s place is very nice. Close to Kokubunji station and you can find cafes, restaurants, shops around the apartment. Lovely and quite local neighbourhood.
Size of the apartment was actually a bit bigger than my expectation (which is good) and I should give 2 thumbs up for cleanliness, LOVE it. With complete amenities as well.
Tommy’s direction was very detail and precise so it is very helpful to find the place or following any instructions during check in/out.
