Hotel is very well presented with helpful and polite staff. Best bit is the location - above Nankai Namba station with great shops and top-end department store below. Just around the corner from Dotombori (best place in Osaka for foodies) and Shinseibashi (best for shopping). The quality of the hotel decor and facilities is great.
Nankai Namba is an excellent location if you are going to Koyasan - we caught a train from here to Koyasan for an overnight stay. We left excess luggage at the hotel and picked up the next day on our way back before heading off to Kyoto. It was very nice of the hotel to keep our luggage an extra night after we checked out.
