Eros is not reputable from my experience at least; if by reputable that you mean that all of the ladies posting ads on eros are verified to be legit providers, no up-charges, no scams, etc.  There is a photo verification but as far as I can tell that is it.  I have had more bad experiences from eros than from any other source FWIW (of course if you stick to ladies on eros that are reviewed here, you are fine).

I think she is legit for the reasons below, but that doesn't mean you will have the time of your life or that it won't be a wasted appointment.

If you click on the lady in questions Web Site link from the eros page, you will go to her website.  Under the "FAQ" section of the website there are a couple of interesting points to note.  First, she only does outcalls which makes it less likely that she is a total fraud IMHO.  Second, she seems to imply that she accepts verification from P411 and RS2K.  I could not find her on either service (p411 and Rs2K are two very reputable verification services fyi, and well worth joining), but she may be under a different name so if you are interested in her I would ask her what name she uses on those sites and if she is in fact verified herself.  I do not have experience with date-check (also referenced on her site).

Also, I recognize this particular lady from a sugar daddy dating site.  I chatted with her over several days for what its worth, I really do think she is legit (assuming she is the same lady as in the pictures).  However, I can't vouch 100% for her because I decided not to see her because she after talking with her for a while I decided she wasn't my type.  I am not going to disclose specifics, but I will tell you that it is unlikely that a scammer would have put the time and effort that she put into the conversations with me over several days.  My guess would be that (as she says on her web page which is consistent with what she had told me) she developed a taste for (much) older men and wants to explore that while making some money for school at the same time.  I would also guess that she is very new to the escort scene as some of the things on her site don't make much sense (for example, she appears to charge more for a striptease with "no club rules" than she does for an hour long session?!).    

I would expect newbie issues, and I would expect she may be very much YMMV depending on whether you are the older, successful gentleman type that she is interested in or not.  

Good luck!
