It's a decent agency but why they don't list services is beyond me. It is a bit of a lottery but there are some gems who are only available through agencies - the aforementioned Lucia for one - who is probably the closest you can get to a guaranteed great punt in London (her attitude is just amazing - that is the thing that sets her apart from most others).
I check for services against Hot Collection, I also use and/or cross refer against Diva escorts as their information on availability is usually bang up to date.
There are some lovely girls on Admirals (mostly available on a few other sites as well) - Nicole (hottest tightest body ever, lovely girl), Jessica (also an indie aka Sexy Sandra - a goddess), Julia (lovely body, beautiful face, very very vanilla service), and Beatrice (big meaty puppies but a toned and firm stomach - love that combination).
The overuse of photoshop is a real pain - e.g. Nicole is much better looking than you would guess from the pics, and the downside is, for Jessica, she looks photoshopped to hell but she actually does look like that in reality - which is incredible - but true. I think the agencies would really benefit by putting up some selfies or more genuine pics, I for one would prefer that and I think they may be surprised at the reaction it got - but I guess, as most of the agencies seem to use the same photoshopped pics, that the formula must work - maybe it's more effective to attract pissed up guys who punt at the last minute?
