I am about to book a hotel for our trip in Osaka for December 24 to 28. We are family of 2 adults and 2 young teenagers. Considering the safety and convenience of the location, I have been having a hard time choosing between this two hotel: Ark Hotel Osaka Shinsaibashi & Hotel Shinsaibashi Lions Rock. Lions Rock have family rooms that can accommodate four of us. We are still awaiting for Ark Hotel's reply if they can provide us interconnecting/adjoining rooms for two double rooms.
