Students on the program either live in apartments or home stays.  Students electing to live with a family must have functional French language skills.  Trinity College works with an organization called Paris Academic Rentals, who secures housing for Trinity in Paris students. 
After being accepted to the program, students will complete a housing questionnaire and will be assigned an apartment or home stay family accoridngly.
The apartments and home stays are located throughout the city and belong to private individuals who rent their properties on a short-term basis. As a result, the apartments are located all over the city and vary in size and condition but are all located in central Paris, in safe neighborhoods.
