I recently stayed here for 2 nights and was very satisfied with the hotel. I chose it because I was travelling to and from via the bullet train and wanted a hotel close to Shin-osaka station so I could drop off my luggage before sightseeing. The Via-inn is a few minutes walk from the Higashi (East) exit of the station - I was unsure at first but there are maps in the station itself advertising the hotel's location so it's easy enough to find in the end.
To get to central osaka it's a simple matter of catching the JR line or subway from shin-osaka station, it only takes a few minutes so it was very easy to go places.
The hotel staff looked after my luggage both before check-in and after check-out and were all very nice. My room was on the 8th floor and it was great, very decent size for one person, particularly in Japan where rooms are never huge!
Breakfast was included in my booking - quite basic (bread, onigiri, yoghurt, fruit, salad, miso soup etc) but it definitely does the job and for the price I couldn't complain. There are computers in the lobby with free internet as well which was convenient.More
