This is long, sorry. TLDR - black mould in bedroom, thick dust, bathroom in disrepair. Owner wouldn't refund anything, left a week early. Please see images.
We stayed in Portugal- booked through Booking.com. Hotel was not as described and was dirty - Booking.com have refunded the commission but said they can't do anything else. They haven't published photos on my review despite publishing photos on my other (good) reviews, and they have not made the venue change the things that are factually incorrect in the listing so others can be misled.
The listing states that the room has a terrace and hot tub but there is no hot tub on the premises. They claim hot tub refers to the spa bath but that is also listed separately. The 'suite' is listed as private access but is just normal access through the main building.
More important issues were that there was work going on every day to put plastic decking around the pool which we were not told about in advance, and they were using electrical power tools right next to the pool while guests were in it. Extension leads were run across the lawn / footpath to facilitate.
Lastly it was dirty and had black mould all across the bedroom wall. Bare wiring on the vanity unit in the bathroom, stained bed linen, broken floor tiles and broken tiling around the stained bath - it's extensive. I have photographs to support all complaints.
we tried to ask for money back to leave, the owner refused. Booking.com were no help. We checked out a week early and paid to stay elsewhere. I feel the accommodation fell way below standard and we should at the very least be refunded the nights we didn't stay - the owner has admitted he sold the room so has had double money. I've tried to keep this to main points so may have missed some relevant info, and can only upload some images but they show the condition of the room.
