Just 1 block away from Esaka station, which is 2 stations from Shin Osaka station. Nice location that when I left Expo Memorial Park station at 17:15 (~30 min train from Esaka) and went back to hotel to pick up my luggages, I can still catch the 18:03 Haruka (not recommended, very rush XD), resonable price,room has enough space to open suitcase, they even have a Vacuum jug with iced water pre filled in room
