Where to live in Brooklyn?

My boyfriend and I are moving to NY in June and I’m trying to scope out the rental situation early so that I won’t be too shocked when I get there. We are hoping to find somewhere in Brooklyn for between $1200 and $1700 a month, aren’t looking for roommates, and value a safe neighborhood and a fun/hip environment (coffee shops and bars within walking distance, cool music scene, etc) over lots of space or a new building with amenities. Is this a possibility? Any tips on neighborhoods to check out? If I’m dreaming here, what are some more reasonable expectations? Any other advice on moving to the city is also appreciated. Thanks!
