The capsule hotel where I stayed the first two nights. For about $35/night I got to crawl into this comfortable little hole (which even has a little TV folded against the wall!), and have access to their super-sweet sauna with cold and hot baths and steam rooms. Not a bad deal, but the complete lack of privacy would make this place a bit uncomfortable for the ladies. I didn't say anything that said "guys only", but I only saw men staying there.
