1) Super location - close to airport bus, Shibuya train station, eateries, 24h convenient stores, cafe
2) response from host was also very fast
3) very spacious room for three,
4) area safe and quiet
5) great accessibility even with 4-5 big luggage from airport bus drop off (excel hotel / Mark City) to apartment.
6) if you intend to visit Mount Fuji on your own, just grab a direct express bus from Mark City - I got mine on the spot last minute.
I will stay in this apartment again for my third return trip to Tokyo.
