looking for an accommodation in Ljubljana

Hello

My name is Héloïse, I am a master's student (1st year), in Nanosciences and Nanotechnology, in Marseille University, France. I've never been in Slovenia, but I love this country thanks to lipizzaner horses (I've been a rider for 20 years, in France), I would like to know this country and learn Slovene. I also need to improve my English.

I will do a three-month internship in the CENN Nanocenter, in Ljubljana (I must start it in April), because I am interested by this laboratory.

I'm looking for an accomodation for 3 or 4 months (April, may, june, july), in Ljubljana; I don't mind being alone or with a roomate (as long as there is a nice atmosphere).
