It does for me... and obviously I am prepared for a bigger donation. Recently saw a lady who advertised she only stays at 5 stars properties.. ended up in a cheap hotel downtown LA... I almost left ( I should have... given the date also was disappointing ).
Also important is that the room be clean and smells nice.. it is. turn off when you show up, it smells of weeds, pizza on the floor.. and major turn off is to see used condoms in the bathroom... all happened to me with " high end" companions...

When her three year old comes into the bedroom because she woke up and got scared does have a tendency to make me wonder if returning is a good idea or not. Yes. It does sometimes.

yes a good environment helps and can make the difference between a repeat or not.     but as long as the place is reasonably clean and quiet thats the major item.   i used to meet ladies at a Best Western,   certainly not fancy, but the room and bathroom was kept clean and area was quiet, so it was fine.  

but i do notice when a lady sets up a nice incall environment.  can certainly add to the experience.    at the other extreme, i once showed up at a place and upon entering could see the bed was a total mess,  food on the floor,  etc - i turned around and left.    

one incall the 1 year old was in the crib in the room.  took a few minutes to handle that but the girl was so nice (and hot) i didn't mind  LOL .  thank goodness baby didnt start crying !   LOL    

Close to my worst incall experience:  The incall was a small studio and my provider had a loose bulldog who was overly affectionate.  This dog was constantly making a beeline for my jewels and I was constantly pushing the dog away from my nuts, to the point where I had to cut the session short!
Seriously, to answer your question, the incall should be clean and neat, in a safe neighborhood, and with no sign of other clients.  I love it when my host has made an effort (music, candles etc.) to set a romantic mood.  It makes a difference!
