I have been to Sweet Paradise three or four times, and have generally been happy with the quality of the girls. However, the rooms are very dark (I like to see what I'm doing), no owo, and I always thought I could do better for the money. So I started checking out privats.
My favourites (in roughly the same area as SP) are Lucumburska 28 and Linda Privat. You will find them (and dozens more) on Escort.cz, and in the case of those two places the pics are definitely real. Prices are about 20% lower than SP. Generally 1000kc /half hour, 1500 hr. Young fit girls who enjoy their job.
