Erotic and other relaxing massages in Monaco are one of the favourite pastimes for its absurdly rich inhabitants. Like everything else it’s ridiculously overpriced, expect the session to cost around €500 and that doesn’t necessarily including the fun stuff. A few touring girls openly advertise massage érotique or massage naturiste, as they often say in French. Check out for instance: Keira Massage (https://keiramassage.com/). Also outcall services such as Monaco Erotic Massage (https://www.monacoeroticmassage.com/) operate internationally and will be more than happy to hook you up.
Some sensual massage studio franchises have also made their way to Monaco. One of the most solid ones is the immensely popular Tantra Home (https://www.tantrahome.com/). It’s conveniently located at Boulevard Louis 2 in Monte Carlo, Monaco’s most famous and central city district. Calling a masseuse or escort with massage skills over from the nearby Nice is also an option, especially if you’re watching your budget.
