I found them by chance and some of the deals seem pretty good for parts of the UK I"m going to. Not last minute bookings, several months ahead. I haven't had a lot of experience with these sorts of sites, just booking.com which went very smoothly. The prices are also per room which is ideal being a solo traveller.
So is this a site that's safe/legit, does it have any more or less problems than other 3rd party booking sites?
