I've decided to check out the selfie museum (the first out of the two in Budapest) and I was pleasantly surprised! I had to ask around before we went if we are allowed to shoot and they were absolutely open to it. The only ask was if we do lewd photos, we should keep an eye out for other customers and children.
The concept of the place is kinda weird in itself, I don't think it's wort to go there for anything but a photoshoot, but for that it's awesome. The ticket is cheap (cheaper than renting a studio) and you have no time limit on your stay as long as they are open. We went during the day so there was like 5-6 people walking by over the two hours we spent there.
But if you go and do a photoshoot there, I recommend you bring at least a small flash (we brought a larger studio flash), because the lighting at the place is pretty boring and flat.
There is lot of rooms with different decoration, but since I like to focus on a single theme at a time, I mostly worked in the pink themed rooms. I will definitely go back and farm the place a bit more, I think 3-4 photoshoots can be easily be managed. (There is also a second selfie museum that I haven't checked out yet).
I also asked them about nude photoshoots, they didn't have an answer right away, seems like it's not a common ask, but they told me that there shouldn't be any problem with it, but it's not a standard ticket - I will have to write them an email, explain what I want and probably can rent out the place for an hour or two so there are no other visitors. They couldn't tell my a price for that yet.

We shot the pictures on a KINO 250D (standard 35mm), which is supposed to be a film produced for cinema and packaged into cartrdridges by Café Analóg. It's not bad, but I expected a bit more from it (I have shot everything on default ISO and didn't push the film, maybe that was my mistake) - but you can judge for yourself! The film is cheaper than most high end films and the development of the film is also included in the price (the scan is something you have to pay extra for).
Keep in mind that they most likely won't be able to develop this film in other places!
