Here is an update from Paragonya, I went Thursday last week.
I arrived just 25-30 minutes after opening and already there was 6-8 providers there. First I must say that the place itself is spotless, newly renovated and very nicely so. The staff is super friendly and helpful, it is super clean, modern and the bar offers drinks and a light food menu (toasts ++).
I stayed for about 5 hours, and I guess the total of providers in that period was 20-25. I was seriously in heaven, it is truly like being a kid in a candy store :). The boys are of course all different, some latino, some eastern european and a couple of asian. Some slim, some built, some xxl and some smaller. Most of them are tops, but so am I so with some negotiation and getting to know them we figured it out so everyone had fun. They do of course approach you and offer their service, but they are very polite and not pushy at all. If you say you are on a break or not interested they leave you alone.
I will not go into much detail about what I did with who, but I will say I had a great time with different boys, two 3somes and I am almost glad I don't live close to this place or I would be serious financial trouble...
Zurich is super expensive (extremely so) but the regular price for a hook up is 100 for whatever is agreed. They accept both Euros and Swiss Franc, and this is super duper cheap compared to online guys from Hunqz or RM for instance and the price level of every thing else in town.
I stayed in the Scheuble and this is super close (almost next door). It is was clean, nice and even though I did not I understand that it is very convenient to receive company (no locked doors to get to rooms etc). Quite a few of the boys at the sauna offered this option but when I left there I was more than satisfied for the day.
I also truly love Thermas in Barcelona, the boys there are cheaper and more pushy and the place is not as nice as Paragonya. I also find it a bit more of a language barrier there as I don't speak Spanish. But they are similar, and I would truly recommend both but plan ahead, save up, be honest about what you want and expect and I promise you a good time.
