I haven't used the brothels but I frequent Munich alot for work and use agencies a fair bit.
Reputable agencies are expensive, 2hours is the minimum for roughly 500 EUR.
Some recommendations:
External Link/Members Only External Link/Members OnlyExternal Link/Members OnlyExternal Link/Members OnlyExternal Link/Members OnlyPander is ok, but the photos can sometimes be deceptive. I've had some pretty medicore ones (they really stand out when your forking over that much!) and some incredible ones. The comms are hit and miss but no issue if you book a couple days in advance.
Lea (600/700 starting) and Etera (800/900) are the premium and are fantastic, the receiptionists are very eager to make a booking happen and the girls are absolutely stunning.
BB and SP are good in comms, limited selection in Munich compared with the likes of Frankfurt and Hamburg. Never had a bad experience booking with them.
Biggest downside to punting here is the rules re oral. It is mandated by law to be covered but there's plenty of girls who will do OWO. You're always taking a gambe when making a booking on that front.
