Gracery if Kabukicho is the point of the trip; the APA tower if you want a pool, a quieter east-side address and more facilities per yen.
Geography is the whole product difference. Gracery sits in Kabukicho, five minutes from JR Shinjuku, with Shinjuku Gyoen 0.6 km away. The APA is in Ryogoku: Sumo Hall 0.2 km, Edo-Tokyo Museum 0.3 km, Tokyo Skytree 1.2 km, Sensō-ji 2.1 km. Location scores favour Gracery, 9.22 against 8.74, which matches the nightlife-versus-sightseeing split.
Facilities run the other way. The APA lists an outdoor pool, a fitness centre, a garden and a children’s playground; Gracery lists no gym, no pool and no full restaurant, and amenities score 7.20 against the APA’s 8.32. That is why the three-star wins for families.
Room complaints land on both. Gracery’s are small room size and some staff not helpful; the APA’s are slow elevators, small room sizes and pricey restaurant options. Cleanliness favours Gracery, 8.71 against 8.03.
Check-in and check-out tip in opposite directions: Gracery from 02:00 PM, out by 11:00 AM; the APA from 03:00 PM until midnight, out by 10:00 AM — the earliest check-out of any hotel we cover.
