I've seen Clara/Eleyna and a couple of previous occupants of that Farnborough bungalow - who offered a similar service or non-service - but not Poppy.
There was an excellent (neutral) review of Eleyna on here a few days ago, which is 100% spot on.
I would hazard a guess Poppy offers the same identikit Romanian-esque service, ie no FK (it's not on her likes list) or OWO and may be fairly affable without being overly friendly or offering much enthusiasm.
I therefore would bet that a 2-girl service would be fairly mundane and would be a duo rather than a three-some; I would rather spend £100 on an hour with one quality girl, rather than an ordinary 2-girl half-hour, but it's your call. Good luck.
