Absolutely agree that it's essential to encourage reviews - positive reviews are indeed the key to success. Do you have any strategies or tips for this? My friend has a newly-rehabbed bus (turned into an apartment) that he just started renting out. After one of the first people stayed, he sent the former guest a polite message asking for a review, and he ended up complaining about some very minor points and only gave it a couple of stars...
I suppose review strategies could even be a brand new post on its own :)
