Fifth tip for great guest reviews. It really works!
I suggest to visit all best places and attractions in your area and save the exact google location coordinates on your cell phone and send them to your guests. You can also add yours favourite places (location of yours favourite not overpriced restoraunt, where to find free parking place in the centre, beautifull but not so crowded beach...).They will appreciate your informations and enjoy your extra recommendations that only locals know and can not be found in any tourist guidebooks and brochures.
And they will leave you a better review! Try it and see:).
Here is my fourth tip!
