Some 2 bedroom options are listed at the link below under the areas you are interested in
They may be stand alone villas, hotel options, houses etc
There are definitely some under 200 per night
Perhaps also look at Seminyak around Jln Double 6 as there are places like Frangipani Villas, Niramaya, Villa Mango etc
Legian - Puri Damai, Villa Pondok Jawa, Villa R ahasia etc..
Kuta & Sth Kuta - Kuta Royal Complex, AP Inn Apartments
As Clovis said your other option is 2 hotel rooms either interconnecting or adjoining
