Bike parking at City Airport

Has anyone used the bike parking at City Airport?

According to their website, it’s free for bikes but I was just wondering about how easy it is to find a space - don’t want to rollup for my flight only to find there’s nowhere left!

Also, bearing in mind it’s not located in what you’d call a scrote-free area, how secure is it?

I’ve never used it but I have noticed it as I’ve rolled up in a taxi plenty of times. Whenever I’ve been there (normally a Sunday morning for the BA01 flight) it looks like there’s spaces, but I always think to myself “bet it won’t be there when they get back”.

Perhaps someone with real experience can be more helpful!
