Nice web site. The description of what you're offering is nice and clear. Now this is probably a really dumb thing to say - but are you tracking the site's stats such as, number of visits a day, pages visited, time spent on the site? Because if you are then you can see how the stats changed when you changed the prices and the description of the accommodation - which pages were affected? Did any pages get noticably more people or people spending longer on them? And if there wasn't any change, then you would need to start looking at what is driving controlling the flow of visitors to the site, given that it's not the prices or the words. But like I said you're probably on top of all that already.
