Absolutely zero-frills hotel, very straightforward. I really, really like it. I have stayed in multiple Toyoko Inns over the years, and I had nothing but great experience staying. Certainly would recommend. But, if there's anything I am not fond of, it would be the check-in time, which is at 4 PM. I wish it could be earlier.
Regarding transportation, the hotel does provide a shuttle where I could go back and forth between Inagekaigan station and the hotel, convenient. Other than that, It is pretty difficult to go anywhere, although walking is still viable. But, being in middle of an industrial area, I do understand the situation.
