Could anyone tell me if it is easy to walk from Nankai Namba Station to Hotel Monterey Grasmere. We have an evening flight into Kansai and may use the train. Hotel website says a short walk 10 mins but other posts I have seen on here said it is a bit confusing finding right exit. First time in Osaka so making sure we don't get lost if we decide to use the Nankai train. Thanks very much.
