As others have said, the F lounge is pretty small, can get packed and the last twice has been full of kids 'playing on the floor' and running around....far from the 'calm and serene' environment marketed by BA.
I also seem to recall that there are no shower facilities in the lounge which was disappointing after being kicked out of the hotel at lunchtime, having a few hours on the beach then heading to the airport so i was feeling a bit 'icky' should we say.
Food offering was def just a few knarly sandwiches, crisps and plastic cheese. Drinks selection pretty average/standard beers, wines and sprits and softs.
Def not a place to spend any length of time.
