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...
Friendly staff, feels like 4 star hotel, there's sento, near kobe china town just next to it, there's city loop stop nearby, near kobe port and meriken park, near sannomiya center gai.
I went there earlier than the check in time with my family and they let us go to room straight away. Got upgraded to family room for free, which was unexpected. Overall we had a pleasant experience and really good for the money.
The location is so good, near the station. But, the room is not soundproof. Maybe there was a party/ did some games in my neighbour's room, and the people there were so noisy until the morning. I could not sleep well.
