Personally speaking, Roms have a very bad write up on here, however I'm sure out of every ten there will always be one decent one - however that are reams of decent well reviewed girls in the area so I'd be going for those first.
To counter the above, she's likely to have been back home for Christmas / New Year so will be relatively 'fresh' having just come back to 'work' so the timing of that may be in your favour.
TOFTT and let us know how you get on - the worst that can happen is a B&S or being charged for 'extras' or having a shit punt in general. The best that can happen? An excellent punt!
As for getting mugged? I know you were joking there but if it happens at least it'll make compelling viewing in the review!
