I posted on chalets direct looking for a chalet this summer and had a few replies. One in particular looks perfect. I've looked at the website and spoken on the phone to the owner. As an independent operator they're not registered with ABTA or anything similar. We do of course have travel insurance.
One thing that I usually look for when booking anywhere new is their Trip Advisor reviews to get a general feel for peoples' opinions. This particular chalet isn't featured on there at all. Would this put you off?
