In 2010 it’s not difficult to find a comfortable short-term Bali apartment rental priced at $50-$70 US per night or less depending obviously on the apartment features, and you can negotiate rates of US$25-$35 per night for apartments priced by the week or by the month. In this price range, if you are looking for well-located Bali apartments Legian and Seminyak would be good places to start (the apartments in the residence block of the Jayakarta Hotel, also known as the Jayakarta Bali Beach Resort are a favorite); perhaps you will pay a bit more for Kuta apartments, probably a bit less in Sanur. Remember that in these areas is quite difficult to find any tourist class hotel (three-star or higher) rooms for less than US$60 or $70 per night nowadays, especially in the high season.
Bali hotels in tourist areas would almost never lower their prices for a stay of 10 days or two weeks or less. On the other hand, the real estate market in Bali has changed, and so as you search online for apartments you are likely to find owners/agents with whom you might be talking to be much more flexible. So, for a 10-day Bali holiday you would be lucky to have hotel accommodation expenses of less than US$700 or so, unless you don’t mind adjusting your standards a bit; with Bali apartments you can expect more amenities at a lower price. For a two-week stay in an apartment in Bali you shouldn’t have any problem paying 60% or 70% of the price of a hotel room for nice apartments or Bali condos with many more creature comforts.
Regarding Bali villas, one normally would expect to spend roughly US$80-$100 per night at the very, very least (up to as much money as you have available!), though again obviously for rentals of more than a week or 10 days one can negotiate better rates. Staying in a villa is a wonderful experience, but for visitors who are more price-conscious and interested in putting money toward a longer stay rather than luxury, apartments in Bali are a more practical and in some ways superior option. It’s not an apples-to-apples comparison, but you can be sure that, especially for longer stays, an apartment will be vastly less expensive than a villa. Additionally, regarding Bali apartments one bedroom units would be by far the most frequently available on the rental market, as residents or expats with families will most likely live in villas; you’ll find far fewer 2-3 bedroom apartments for rent. For one person or a couple, apartments are more attractive price-wise than an entire house.
Aside from accommodation costs, remember that compared to a hotel stay your cost of living will be lower because you will probably spend less on food. You won’t have to go to a restaurant every time you are hungry; having a kitchen or kitchenette gives you choices, and especially if you have children you might really appreciate this flexibility!
