We spent an idyllic week at the Wriggly Tin in early July. It would be hard to find a more perfect place. The house is very spacious, with a wonderful large kitchen and dining room area with great views, a comfortable living room with a big-screen TV (free movies!), four bedrooms, and 4-1/2 baths. Everything is modern, immaculate, and decorated with real taste.
Karen and Peter go out of their way to provide for their guests. This starts with the welcome package of a giant chocolate bar, home-made flapjacks, supplies of coffee and tea, milk in the refrigerator, and fresh flowers. There are extra washcloths, towels, and tissues in every room. The chairs, beds and sofas are all very comfortable. There's remarkable attention to detail everywhere; as a tiny example, there are easily accessible electrical outlets everywhere so one doesn't have to crawl under the furniture to plug things in.
The Monsal Trail is literally across the road, with easy walking in both directions. There's a lot of beautiful scenery nearby, of course. Our favorite spot was Peveril Castle, which we visited on a perfect day, but Chatsworth is close, and Ashbourne and Bakewell are both fun to wander around.
We've stayed in a fair number of self-catering places over the years. By a significant margin, the Wriggly Tin is the best we've encountered.
