I also use TA, both to review and also for research, I ignore any reviews where they reviewer has less than 10 posts, so far it has been good to me, with most hotels well chosen. One in Paris that got rave reviews, we had some real issues, although our friends did not, I put an average review on TA, and was contacted by the hotel for further information, I have been offered a discount to return, I will be returning to paris in a few months but will stay elsewhere, not that it was bad but there are plenty more to choose from, if we had a good stay no doubt we would be back, but time to pick something new.
i just stayed at the Sheraton four points darling harbour yesterday, I have previously reviewed this hotel, despite my reviews still has coughpy towels, will make a comment about their towels yet again, but love it other than that!!
