We booked a last-minute stay. In spite of the discount, the rate was still pretty steep. We chose a regular cottage, expecting (given the reputation of Center Parcs) this would be OK. It was the worst we ever stayed in. It was about 20 minutes walk from the main area, which in itself was not too bad. But it was completely surrounded by trees, so we never got any sun on our terrace. We had the lights on most of the day. Interior rather shabby and worn-out. Lots of small things wrong, for which they sent a handyman within 2 hours of my complaint. He fixed most things. But the worst problem was the damp. Everything was cold and clammy, even the mattresses, which made for an uncomfortable sleep. And the sofa cushion stank, there was black mould everywhere, we even got a visit from some slugs.
They totally ignored that part of my complaint, so I will write to them about it. I do know they are refurbishing cottages and cannot do them all at once of course. But they definitely should not have been renting this one out.
