If in doubt, be wary with outcalls. I'd suggest a first outcall is better with someone you can judge to be reasonably ok and you have enough info on to rule out nutters. After the first one, you'll think through your security routine and see if anything needs to be updated.
Even in a hotel there are some risks, over and above being careful with personal effects. I had a close shave in Derby and I'm pleased no-one saw the bedraggled mongrel that came to my room. But staying in Derby verges on desperation anyway (I wasn't desperate, just enjoying the wildside haha). I had an outcall to my apartment abroad where the WG started turning nasty and making threats. Fortunately I was well prepared and read the riot act to her before she finished her sentence.
These are exceptions. Most outcalls are fine, it's easier to get many prossies to stay longer than the time, you can enjoy a decent drink instead of her crappy wine or none at all, you can sit watching some porn as she is on her way, and shag her on a real bed without cum-stained sheets from earlier section's of the 'lady's' working day . . .
A lot of prossies also live in shitholes or use bland tasteless apartments rented with other girls or other places that lack a decent am-bi-ence. Some have made so much dough that you feel like you are paying for the bad choice in art prints hanging on the wall. All in all much nicer to use your own place if everything is properly sorted.
btw - just to throw in a rare complment - I thought Sweet-and-Petite's pad had a feel to it for a prossie flat.
