I spent about three days at Kobe portopia hotel.... close to shiminhiroba Station (Kobe) approximately 100 metres and roughly 100 metres to exhibition hall...
Then, there is a shuttle bus from hotel (free) to sannomiya Kobe station... and you can take a bus near Sogo (in front of sannomiya Kobe Station) which is direct to Kansai Airport....
There are a lot of fancy restaurants inside hotel area...
I took “dine” at Shushiman and Gococu...
