Looking for flatshare/room (Sofia)

Hello! So, recently I made a crazy decision to move to Sofia. Consequently, in oder to make my life more enjoyable here I'm looking for a cool place to live. Currently I stay in a really expensive place close to my job in Mladost 4 but I'm not very happy about it cause I live alone, it's not fun and it cost me a lot of money every month.
I am thinking of finding a place close to the center of Sofia and in convenient location to reach red metro line. In addition to all that, I am also looking for great and fun flatmates to keep the spirit up. So, if anyone has a nice room or looking for an amazing flatmate like me, let me know!
Thanks! :)
