The biggest city in Tohoku, Sendai has so many hotels that it can be difficult to choose. One time, though, one of the websites I use saved me the hassle by offering a deal that was too good to turn down! (I don't guarantee this will happen every time.)
The lobby is a nice welcome to the hotel, with a little lounge area furnished with colourful, comfortable couches and sleek glass tables. The staff were helpful and efficient, giving me a sheet of information in English, and even going as far as to lend me an iPad for the evening when I had trouble with my computer.
My single room was the usual compact size, absolutely fine for a solo light traveler like myself, though the lack of a full desk made it a little tricky to set up my laptop. Instead I had a little cushioned seat and a little table, nice enough to sit at and have my breakfast (my bargain rate included no meals, of course).
The design was simple, modern and stylish, with plenty of woodtones, a full length mirror, and a nice tiled bathroom rather than the molded plastic unit common in business hotels. Little touches of attention to detail made things more convenient; a bag to carry towels to the public bath, light switches for the whole room immediately by the bed, an effective blind and screen on the window rather than curtains.
The public bathroom was good and spacious, with a good range of toiletries, and plenty of room in the bath to stretch out my weary legs and relax after a day at the sights. (As is common in Japan, guests with tattoos aren't allowed to use the bathroom, though that actually didn't stop one Japanese guest from doing so.)
