My wife and I only stayed one night, but enjoyed it. If you're looking for privacy, it's perfect. There isn't much English when coming in but the staff was quick to use Google translate and the t.v. guide can be changed to English. They have a wide array of food, drinks, "etc." for purchase or rent. It was good fun. The sheets weren't the nicest, but if you want to try a themed love hotel, go for it!
