The Hidden Gem was a lovely place for a great price. It is a solid 5 minute walk to the first convenience store, and about 20 minutes to the Split. We only rented bikes one day as we couldn't justify $5USD/day/person but the walk itself wasn't too bad except for the mud.
The rooms were sparkling clean and had everything that we needed- towels (beach and shower), toaster, full sized coffee maker, bedding, and of course AC (which is very much needed).
There is a nice welcome package when you arrive with maps of the island and suggestions on tour groups which was a bonus.
The pool was a wonderful day for us to spend a whole day and we had it to ourselves (shared with the other property but they were respectful to let us be). The private dock was a nice touch, but we really did not use it.
The only complaint was that there was no hot water for the shower/kitchen. That being said, it was so hot that we didn't bother to ask if that was normal or not.
Overall, I would recommend this place to people who want to enjoy the buzz of the island and then be able to retreat to a quiet corner of town for rest.
