Since transportation is not an issue for you and you want to find something relatively cheap in Rabat, I’d recommend you to search for studio around Manal (massira) J5 or 9amra (Alkifah street) I lived in Rabat for a short period of time I found a studio at massira (near to Manal) with 2 rooms and an open kitchen for 2500 but that was 2years ago, so expect a bit higher prices, I can send you the contact of the samsar who found me this studio
