Pro Tip: Know Your Doorcode
One of the surprising things about Paris is showing up here and realizing you can't get into any building without a door code. No one really tells you that. And while most doors are open during business hours, some (like mine) are the rare exception that don't open during these times. So just a quick tip, if you're renting an airbnb or going to someone's flat, make sure you have the digicode to get into the building. And then make sure you have the name on their interphone once you're inside. Otherwise you're going to be waiting outside trying to get them on the phone. And if you're flying into Paris and haven't switched your phone to a French network, good luck with that.
