hey hey crooney55
we all want to be spoiled haha
booking.com (filters in for apt and people, they want ages of kids) read the fine print carefully. what floor and if lift/elevator to carry luggage up, key exchange, if too early for checkin where to store bags or if early is allowed, cancellation policies, minimum stayed wanted?
some of the places we looked at, double bed unless ask or request twins and sofa bed is considered for 2 people. check it is one bedroom, not bed and sofa bed all in one room along with kitchenette and living room, like a studio, look a pictures and read reviews.
cross-pollinate.com
airbnb.com what ever you're looking and hoping for. in description "read more about place" click and registration number starting with 75, if there legal if not keep looking.
may not be exactly where you want, unless budget not a concern, there are shops, bakeries, restaurants, roaming around the areas
the couple places we stayed in before, one is no longer on site and the other went to a 30 day rental
minimum, that's why we ended up in the 14th arr.
adagio and citadines, like others have mentioned.
maybe your daughter that lived there still has a friend with knowledge of something
trying not to preach to the choir, it just took a lot of time for us and i was determined. have a great trip and good luck
