This was the best value hotel we stayed at on our trip to Japan. While superficial elements (like the shower walls material) were not as "nice" as other, more expensive hotels we used during the trip, at half the price of those ones, Sotetsu Fresa was just about equal in everything that mattered to us: room size for the money, bed comfort, cleanliness, amenities available, location, etc.
I would definitely recommend considering the Sotetsu Fresa chain as a strong option if you're budget-conscious. I think you'd have to go up quite a bit in price to do much better.
