LCY is one of the nicest airports to fly out of. All the check-in, security procedures are done professionally and with minimum fuss. Not sure there is a flight direct to Strasvourg, so you might have to change. It is taylor-made for business travellers so is a million times more pleasant than the LHR zoo. I use it for business to Europe and pleasure to connect to long-haul flights via Frankfurt, Amsterdam etc. T/O is a lot of fun too - full power, hold on the brakes then off like a rocket! Landing is a little firm to say the least! But all in all a good experience.
