Looking for a room in Sofia

I am a student in Madrid looking for a room in an apartment/flat from september to february. I don't have any problems living with more than 3 people. In Madrid I've lived for 6 years in an aparment with 4 and my other year in Malaga we were 7 people. I would like to have my own room, it's my only request. I can share a bathroom and everything else.

I'm very friendly and outgoing, sociable and likable and I want to sorround myself with bulgarians or foreigners, whomever would be perfect. I also don't have a problem living with either girls or boys, I've done so for the last 7 years and I've never had a problem with anyone!

Hope you can help me, 

best regards from Spain!
