I highly recommend Lio's apartment for short or long stays. Despite its size, it is very comfortable and fully furnished. One of the best aspects of it is the great location, just right to walk to the center and not too close to the noise of the city.
It is ideal for two people because, although the double mattress is very comfortable, the folded couch is not the best option for sleeping.
Both Lio and his brother Olivier were very friendly and understanding. Thank you again :) We really enjoyed staying in your appartment in Paris.
