We came in late September and had a great experience. Apartment is small but comfortable, and incredibly well located--10 min walk from Notre Dame and Orsay, and 15 min walk from the Louvre. Plus there are plenty of cute cafes and bars to hang out within a 5 min walk, and plenty more around Saint Michel (a 15 min walk). It's a fun, hip area, but completely safe (compared to--say--Montmartre).
