Good points made by all so far. I'll add a little by saying, I don't mind any particular type of incall, as long as it's safe. There's nothing worse than having to go to a location that has yellow tape, potholes all over the place, and shady looking characters pretending to be on the phone as you pass by them.
In contrast, going to a nice, plush hotel or decked out apartment sets a good vibe. Sure, it's a bit of a downer to have to pay for parking or deal with a gate code, but it's not a deal breaker by any stretch (and please, give me the damn code BEFORE I get to the keypad so I don't have to sit there looking like a dumbass who clearly isn't supposed to be there. It's a bad look, especially if there are cars behind me). I like knowing ahead of time what level of an incall I'm going to (5 star vs 3 star). That way I can dress appropriately. Showing up at a low budget notel overdressed looks just as bad as showing up to a towering 5-star wearing NIN t-shirt, ball cap, and Jordans. Just saying. Walking through a football field sized lobby underdressed is as bad as it gets. I mean borderline anxiety attack creating.
It almost feels like everyone in there is thinking LOUDLY, 'Hey, everyone! Look at that, underdressed, fish out of water black guy over there! What is HE doing here?!? He must be going to see some fancy call girl or something! What other reason could he possibly be coming here for?!'
Just saying.
