@Viking11 started at thread on Booking.com but this has more posts and is relevant to what I want to say, so I'll post it here.
Some argue that Booking.com deletes bad reviews - this does seem to be the case.
My sister booked a room through the site at this hotel, East Walls in Chichester. The experience was awful - though it didn't last long!

Now, East Walls hotel has positive reviews across the board at first sight - you have to make the effort to investigate the bad reviews only to get a different impression. Now, I was going to use this to highlight how many recent reviews are negative but hidden, but now I post this I see that there is just one bad review in last month, while the next bad review is a long time ago - and I don't recall that being the case when I checked it out a fortnight ago; so some negative reviews do seem to get deleted.
Indeed, even when you look up the same residence on TripAdvisor, again, it still seems like a safe bet - you have to specifically check out the bad reviews to get a fairer impression, and these are drowned out by 'good' reviews, even if the bad ones don't get deleted.
We hardly got over the threshold before we were booted out - we were subjected to a tirade of admonishment in the first minute, it seemed quite extraordinary, our hostess saying angrily and somewhat hysterically 'If you find you don't like it, just say so, you can leave, I have no problem!' Eh?
Now, some hotels do overbook in the same way airlines do, but many have links to other hotels which can step in should there be no 'no-shows' that night. I suspect what happened here was they had overbooked, had no hotel to take the overspill not being a chain, so the best way forward was to find a pretext to turn away the unsuspecting customer. Other reviewers on Tripadvisor experienced a similar turn of events, one advising not to book via booking.com because the hotel resented them for delayed payments, and they took it out on the customer.
It is easier to find the bad reviews on Tripadvisor but again, the hotel still has a high rating across the board.

The question then is, do you get a refund via booking.com because a good many have found they don't get their money back. You might then instead choose to get your refund on your credit card instead? Problem is, the hotel then has your credit card details and can simply withdraw the same amount from your card the following day without your permission. I'm not saying this is what happened, here, suffice to say the matter is with First Direct's fraud department.
Don't expect the police to get involved; apparently the matter is a 'dispute' and not a police matter!
Many praise booking.com saying they've never had any problem; one suspects it's a numbers game, as with Ryanair; so if something goes wrong, your're screwed but most customers can say it went well, so there you are.
That was our first and last time of going via booking.com!
