29 year old physician on specialization in KC Ljubljana, looking for accommodation from october to 28th of december

I am 29 years old physician on specialization in KC Ljubljana, looking for accommodation (flat/apartment/room) from the 29th of september till 28th of december, 2018. I am coming with my own vehicle so I would like to have parking place. Location is not of a huge importance but it should be in Ljubljana. I would like to be alone (in my own room) and to have my own bathroom, kitchen if possible and Wi-Fi. The desireable price would be till 250 euros.
