moving to Warsaw

Brittany
Okay, ladies! I'm going to be moving to Warsaw, Poland at the end of August to teach English. 
I'm moving by myself. I've been to Poland previously (Krakow), but I've never lived alone (lived with parents until college and then in college, I always lived with a roommate). 
I recently graduated from college (go Dawgs!!) and want to travel/live abroad while I'm young and have very few responsibilities. 
Any advice for a single twenty-something moving abroad/advice about living alone/advice about Poland/TESOL? 
Thanks! xx
