While the location of short term rentals is obviously the most important aspect of them, the next issue will probably be the size. If it's just you or you and a partner, then you may not need something tremendously large. When travelling with kids, having a little extra space is important. Be sure when you start looking through the various rentals available that you find the one that matches your space needs perfectly otherwise you may end up regretting your rental. It should be easy to check the number of bedrooms, bathrooms, and more with a few simple clicks of the mouse.
Amenities make a rental, and you'll want to look into just what your potential short term rentals offer in that respect. All should come with lovely furnishings, but additional features like free internet, air conditioning, television, and more are also well worth checking into. The proximity to things like beaches, nightlife or restaurants is also important and worth looking into. Take all of these points in mind when you start looking for your rental in order to ensure you get the perfect place to stay no matter how long you're planning on staying there for.
That last point is important as well. The length of your stay may actually dictate which of the various short term rentals you choose to stay in. That's because not all are available for the same durations. The best offerings will be available nightly, weekly, or even monthly so that no matter how long you're planning on staying in the area you'll know that your rental is yours. If you'll keep all of these things in mind when looking for your rental you should be able to find the one that matches your specific needs and desires perfectly every single time.
