We had one night to stay in Sendai, and Hotel Vista was perfectly adequate to spend it there. Our room was Japanese-tiny, but the bathroom had a much-bigger-than-usual bathtub. Of course everything is clean, and the staff at the lobby was exceptionally nice. The wifi was fast, and they had a laundry room.
I felt that the breakfast wasn’t worth the price: there are much better places to eat at at Sendai station. The good thing is that the station is very close, only a few minutes of walk from the hotel, so you can find pretty much anything in a small time.
