Hi Pebble,I have stayed at Sendai Higashi-guchi No.1, which could be more than 5 minutes walk from the east exit of JR Sendai station. If you would like a bigger room try "Twin Room B"
I think Sendai Nishi-guchi Hirose-dori is better located .
"4 minutes ?" walk north from the west exit of JR Sendai Station, and in a busier area where shops and restaurants are.
