You might enjoy a 2BR lockoff, so you can let your mother have the studio part and you can enjoy the 1BR section. You will connect, but have your own individual spaces. It will cost you most points to do it this way, but you will have in-room laundry and a full kitchen. If neither of those matter to you, then go with the two studios, but you run the risk of them not being close together. (Not sure how much of a risk -- others can probably chime in on that.)
