I enjoyed my stay at Hotel Nikko! Everything was smooth, professional front desk and concierge staff. Room was clean. The hotel was just above Shinsaibashi subway station (exit 8) & opposite to the main shopping street.
Access to popular area like Shisaibashi in 10 minutes walk, Dotonbori 5 minutes and Bic just next to the hotel. Namba station within 10 minutes, you might go wherever Kyoto, Nara or Kansai Airport within one hour.
I will stay at the same hotel next time when I come to Osaka. Besides, I am thinking to book its link-hotel at Kyoto since service is guaranteed. Room is comfortable and larger than those in Osaka Station, which rated 5 stars, and at much economical price. Shuttle bus service is excellent and rapid. Will recommend others to stay.
