Rose Cottage is in Tenby, on a quiet street about 50 yards from South Beach. It's a Victorian terrace. You're right in the town, so it's handy for everything.
The cottage sleeps four in three bedrooms. There's one bathroom. It's got a 3 Star rating, which means it's comfortable and clean, not luxurious. The stairs are typical cottage stairs, so they're a bit steep.
You've got a shop, a pub, and restaurants about 200 yards away. The beach is just down the road. It's a good, sandy beach.
The cottage has a slate floor in the living area and an old fireplace. The kitchen is galley style, so it's a bit narrow. It works fine. There's a TV, WiFi, a washing machine, and a dishwasher. Bedding and towels are included.
Tenby itself is a walled town. The harbour has the classic view you see on the postcards. The Pembrokeshire Coast Path runs right through here if you want a walk. Boat trips go from the harbour out to Caldey Island, where the monks live.
Within about half an hour you can get to Oakwood theme park, Folly Farm, or Heatherton. There are a couple of golf courses very close by. For a longer day out, you can drive to places like Pembroke Castle or around the National Park.
No pets, sorry.
