Smile Hotel Tokyo Nihonbashi, Tokyo

Perfect for the tourist on the go! Small rooms don't matter if you're just there to sleep. The biggest selling point is the location, almost directly on top of Kayabacho subway station, with access to the Tozai and Hibiya lines. You're also no more than two stops away from every other subway line in Tokyo. Friendly, helpful staff makes the stay most pleasant, the restaurant is convenient and has a nice breakfast buffet (1,000 yen), and you're mere steps away from a Japanese pub, a convenience store, a post office, and a great little stand-up udon joint. Finally, this hotel is a great deal. You're right in the middle of everything, but a single room can be had for as little as 6,200 yen per night for a single room, if you book online. I stayed for two weeks, for less than US$1,000. Highly recommended!
