Every Review has a field for "Session Location." However, there is considerable ambiguity about the meaning and even how specific to be.
.
The Major BIG ambiguity is that some reviewers think it means GEOGRAPHIC location with varying degrees of specificity:  
New York, Los Angeles, Boston, ...  
or at higher resolution:
Manhattan (NYC), K-Town (LA), Back Bay (Boston), ...
.
But some reviewers interpret that as the alternative option and specify the type of real estate location:  
Her Hotel, My Home, My Hotel, Her private location (apartment or rental), AMP apartment, Studio apartment, ...
.
The geography component is useful because it better informs people using reviews about where that hostess has actually hosted. I.e., her "City" location, further down in the Review specs, is usually her HOME city or home base, even though she may tour all over the US or World. If that hostess has reviews in Geographic Locations NYC, LA, and Boston then a potential client knows that she has actually traveled to and been seen in those cities and not just her HOME CITY.
.
Another plus that came up recently: Sometimes Providers want to dispute a review. If the Geographic Location conflicts with her actual schedule, she can appeal to TER and, as happened recently, point out that the client Reviewed the wrong Provider with the same (or similar) name. E.g., Mary might appeal to TER that "The reviewer claimed he met me in Chicago (within the past 3 months, the TER limit for reviewing a session). My TER Ad Board posts clearly show that I haven't toured to Chicago in over two years. The review is either a FAKE or the reviewer meant to review a different provider named Mary. Please remove it from my Profile."  
.
Likewise, real estate location of the meeting is useful for potential clients, too. "Her hotel" clearly says she does incalls. "Back seat of taxi" clearly says, "I think I'll pass." And so on.  
.
I SUGGEST that TER modify the next gen Review forms to be more clear about SESSION LOCATION.  
.
Option 1: ADD another field and rename both fields: "Geographic Session Location (City)" and "Real Estate Session Location (e.g., hotel)"  
.
Option 2: ADD a clarifying note or example to the review form: "Session Location (CITY where meeting took place)." OR "Session Location (type of real estate where session took place, e.g., hotel)."
