To me, the Yamatoya Honten is the best hotel that you can find in the central area of Namba. After have stayed in few hotels in this area, I discovered the spacious Japanese-style room and nothing was missing; ie a large bathroom, fridge, yukatas(Japanese traditional clothes), secured storage facility and even the famous Japanese tea served everyday. The staff was so kind, always with a smile and very helpful. I really recommend this hotel for a comfortable stay.
