Sylvia’a place is adorable and even though it’s a bit further out of town than mega central the tube system is easy to navigate and very cheap ! Lots of bakeries and general food places/supermarkets in the area if you wanted to eat out or cook.
Despite the language barrier (I understand French much more than I can butcher it), checking in and out was seamless and Sylvia was very helpful in storing our bags and ensuring we left in enough time to brave the chaos that is CDG airport. Would recommend !
