Please review my startup Ventoria.com
pedalpete: Well, it seems you have a great service for Chamonix, and that's a good start. 
I live in Whistler, and have been somewhat affiliated with this market in the past.From a usability perspective, your homepage didn't really make me want to click on anything. It didn't make me want to enter a search. 
You've got a great big photo of a mountain, and you tell me what you do, but I often prefer to be 'shown'.Basically, i think you've got a bunch of text, and actually using the service looks to be somewhat secondary.Once I actually go to the listings chamonix/accomodations page, the layout isn't super easy to browse through. 
I use a 3 column layout like you do for featured items, but find a list much more easy to read when you have lots of listings.The accomodation view pages I really quite like. This is of course one of the most important pages on your site. It is very clearly laid out, and usable. Lots of pictures is good, etc.what is your plan on spreading this beyond Chamonix?i took a quick look at some of the top google results for 'find location properties', and the first few results were not very appealing, which is very surprising. you may have found yourself a good market here.
