Checkin at 3.00pm is hopeless Lobby is small, so luggage storage is hard, and when you have been travelling/flying long hours, earlier access to the room would be better. The rooms are quite small, eg, if you have two medium/large suitcases, you have to take it in turns to open them, as not enough space for both at the same time. Staff are friendly and try their hardest, but in our case, we needed English language, it was very hard with communication, even though we have basic Japanese.
Very close though to Tennojji Rail hub, Q's Mall Shopping Centre, and numerous small shops, so picking up breakfasts/snax etc really easy.
