I am staying in Ljubljana for a few days and I found out this massage parlor on this website and also banners on the street. But this experience turned out to be a really terrible one and I was ripped off. I'll explain in point forms so it looks clear.
1. THIS IS THE MOST IMPORTANT POINT!!! The boss of the parlor introduced me with different services. I chose the most expensive one which is 120 Euros and it's body to body massage for 50 minutes. However, there is no body to body massage and the massage ended within 15 minutes. I was really pissed off and I asked the masseuse and the boss and they both said it's 50 minutes. The boss even said he'll compensate the time for me if I go there again! This massage parlor clearly ripped tourists.
2. The claimed University-aged masseuse ladies is false. I was massaged by a lady who has big ass and nice boobs, but she is definitely not University-aged and she doesn't look like local girls.
This was actually my first ever experience of an erotic massage and I was really angry that it turned out to be a terrible experience. If you travel in Ljubljana and you are finding a place for good erotic massage, never go to 1st Sun Salon or you'll end up like me.
