I'm a 23 years old student from Romania,I'm in my 5th year at the University of Medicine and Pharmacy of Targu Mures.We are 3 medical students from Romania who are going to do a two months placement in the Montpellier Hospital. We are very friendly and speak decent french. We are looking for a place to stay in the city centre and close to any public transportation, preferably the tram for easy access to the hospital.
