it’s just such a clean airport. the signs are clear where to exit and the nicest of all – the suitcase karts are free! I’m used to having to pay a dollar for a kart. A very spacious airport with plenty of people all around to help. I had to buy a metro ticket – you can buy one from the yellow booths but you can’t use cash there – just a tip. Also, if you’re not so sure, it’s just best to talk to one of the people at the counter. Something I didn’t know until I got lost and it was too late: they call the subway the “metro” =)
