I've done it along with most of the guys here. That is usually the default. Not a comprehensive list but:
Their Place Pro
-cheaper
-much more likely to fit you into their schedule if they are busy (most top girls are busy of course)...they just need to find one hour instead of 2.5-3
Their Place Con
-you have to travel
-you might not know the area
-you might arrive and they don't answer (not common but it happens)
Your Place Pro
-easier
-safer if you have a doorman checking on them/ID/double-checking on you before he lets them leave, etc.
-can still be shady, she likely won't drug you with security precautions but she might still have sticky fingers
Your Place Con
-$
-some of them will say they are one the way but never show...they will dick you around instead of you doing the dicking.
You can mitigate many of the cons by using girls who are well reviewed here

In the U.S. the cost to get them to come to your place is 20-30% higher on average from what I've seen. But in Medellín it is 2-3x as much. No joke. Between the lost time for more appointments and traffic/travel hassle, they have to make it worth their effort.
Now if a girl is $20 then paying $50 is not a big deal for many us. I did it once because it saved me about a total of an hour travel time and I had a bunch of stuff I wanted to do. The extra $30 was worth it so I could fit more into my day. That being said, with a little planning you don't need to do this every time.
As far as Laureles in-call goes: A ton of the top reviewed girls not only have their own place, but they are in Laureles.
In the end, it is like most things, you are balancing convenience and price. Safety, etc. can be mitigated with using common sense and sticking mostly to well reviewed girls.
