If you've never stayed in a Japanese love hotel, it's interesting and probably worth it if you know what you're getting into. It's probably overly clean (e.g. towels are packaged in plastic so you know they're clean), it's efficient, and spacious for a Japanese room. Minor things make it less ideal for business (no desk in my room, slow WiFi), but great free breakfast. Other things are just a part of the experience (occasional porn in TV, blackout curtains in public hallways for privacy, overly spacious bathroom with built in TV).
