We had a great stay at Tomoko's appartement. Yes it's small and maybe a bit dated, but hey, you're in Tokyo! The appartement is only a couple minutes walk from the metro station and in two stops you're at Tokyo's busiest station, Shinjuku. Also, Tomoko is really nice. We had a smooth check-in (which was really appreciated after an 11 hour flight with no sleep) and she escorted us to a ramen place and helped us with ordering. All in all a good experience!
