After many years of hotel stays in Paris, we finally decided to rent an apartment. And yes, we rented for 1 week at a time or 10 days. It opened a whole new world of Paris to us. We actually felt like we were living in Paris ... not just visiting. We enjoyed shopping at the open markets and not having to have every meal in a restaurant (which gets really old after a while). We enjoyed making coffee in the mornings and having at least one other meal in the apartment. We used Paris Luxury Rentals and it was such a good experience that after a few years we actually bought an apartment in Paris. I would highly recommend renting especially since you would not be able to all stay together in one room in a hotel.
Hope this helps!
