Servisair lounge LHR T3

Done a search on servisair lounge but it only comes up with Gatwick, Manchester and Glasgow.
I'm going out on VS003 on 31st January in PE. As previously posted I will be arriving at check in early to try and get a window seat in row 18.
This then leaves me about 2 1/2 hours before the flight. The question is,is the servisair lounge any good and what can I expect.
I've looked at the BAA website which gives a brief description and the charge is £17.95 which seems resonable to me. So should I book?
