The apartment is easily reachable and other Paris attractions are quiet close by. We did most of the places by uber., it worked for us for 4 of us. (2 adults and 2 kids). Versailles we bought tickets from st Michel Notre dame on metro and it worked well for us. Enjoy the nearby cafes, markets which are reachable by the walk. We even walked to the louvre.
We did the impromptu boat ride from near Norte
Notre dame which turned out very good. It took 1 HR for this ride.
