One word: Excellent!
Perfect location (the neighborhood is lovely - nice cafés/restaurants, cute shops - lively but very quiet also). A few minutes walk from Roppongi, easy and very quick to reach Shibuya, Shinjuku, Shimbashi and any other Tokyo's centers by the transportation.
Akari's place itself is just ideal for a couple (and probably still very nice for a family or 3 or 4 people). Very new, very clean apartment. Simple but cute and functional place. Last but not least, the balcony with its Hammock and great view on Roppongi brings something very special to this lovely home!
Akari is easy to reach and communication with her is fluid.
Definitely one word only: Excellent!
