The same apartment can cost you wildly different amounts depending on how you book it. Plenty of people stay in Da Nang for months while still paying nightly rates, simply out of habit.
Here is the arithmetic.
Why nightly costs so much more
Three reasons, all reasonable from the operator's side:
Platform commission. Booking platforms take a percentage of every reservation, and it is priced into what you see.
Turnover cost. A two-night guest and a three-month guest both require one deep clean, one set of laundry, one inspection. Spread across two nights, that costs a lot per night.
Vacancy risk. Short-stay letting means empty nights between bookings. The nightly rate has to cover them.
A long-stay guest generates none of those, which is why the monthly rate is lower. It is not a discount — it reflects a genuinely cheaper arrangement.
The numbers
Take a one-bedroom in Da Nang at 750,000 VND per night, or 13,000,000 VND per month.
| Length of stay | Paying nightly | Paying monthly | Difference |
|---|---|---|---|
| 7 nights | 5,250,000 | — | nightly makes sense |
| 14 nights | 10,500,000 | 13,000,000 | nightly cheaper by 2.5M |
| 20 nights | 15,000,000 | 13,000,000 | monthly cheaper by 2M |
| 30 nights | 22,500,000 | 13,000,000 | monthly cheaper by 9.5M |
| 90 nights | 67,500,000 | 39,000,000 | monthly cheaper by 28.5M |
Break-even lands around 17 to 18 nights. Staying longer than that on a nightly rate means overpaying.
Over three months the gap is roughly the price of three flights home.
What you trade away
Monthly is cheaper but less flexible.
Deposit. Usually one month's rent, returned after you move out. So your first payment is effectively double.
Contract and notice period. Leaving early means giving notice, typically 30 days. Not the two-day cancellation you get on a booking platform.
Utilities billed separately. Nightly rates usually include everything. Monthly rent is rent — electricity and water come on top. Budget roughly 600,000 to 1,200,000 VND per month for one person and include it in your comparison.
Cleaning. Short stays are typically cleaned daily. Long stays vary: some places clean periodically, others leave it to you.
How to decide
Under two weeks — book nightly. Flexible, no deposit, no contract.
Two weeks to a month — ask for both prices and do the sum. Many places have unlisted weekly or half-month rates. Just ask.
Over a month — always ask the monthly rate first, even if you are not certain how long you will stay.
Not sure yet — take one month and extend. Far less risky than committing to a year before you know whether the neighbourhood suits you.
How to get a monthly rate
Many places do not list one on travel platforms, because those platforms are not built for it. Almost everyone has one anyway.
Message them directly: "I'm planning to stay around three months — do you have a monthly rate?"
Then ask:
- What the monthly rate includes, and how utilities are billed
- Deposit amount, and when it is returned
- Whether six or twelve months gets a further reduction
- Whether you can extend month by month, or must commit up front
That last one matters most if your plans are uncertain. A place that lets you extend monthly is far more forgiving than one demanding six months on day one.
One practical tip
If you have found somewhere you like on a travel platform, search for the property name on Google or Facebook. Many operators have their own channel and price direct bookings lower, because they are not paying commission.
This is entirely above board and better for both sides. Just confirm you are dealing with a real operator — the warning signs are worth knowing before you transfer money to anyone.
RentalFM lists both nightly and monthly rates on every room, so you do not have to ask to find out. For stays of a month or more, the monthly rate is well below the nightly one added up.
