I was a little hesitant with Retretia because of all the bad reviews and low star rating I saw. BUT, after reading through them, I realized 99.9% of them were over people not getting refunds due to the pandemic. While I certainly understand that frustration, they were beyond crystal clear when we rented that there wouldn't be refunds issued for that, or weather, or whatever and recommended multiple times that I buy trip insurance. So I think most of these negative reviews are pretty unfair and unreasonable.
We pulled the trigger and rented through them. What I can say is that during the entire stay, they were incredibly kind, responsive, and helpful. They addressed issues promptly. We had a broken hot tub during the majority of our stay, which was frustrating. But, that isn't their fault. They sent the repair folks out same day or next. They struggled to get it going, but again, I can't really fault Retretia for that. We've rented a ton of VRBO's. And there are usually some small issues with them. This was definitely the best experience I've had with a rental company thus far though as far as responsiveness.
I can't speak for negative reviews about the quality of any particular rental. I guess I would say to look at those reviews separately. We stayed at Sky Valley Lodge, and it was very very nice. Spacious. Easily accommodated our very large party. Had more than ample parking. Beautiful views. It was clean. The decor was great. Easy access to town.
