We've made the decision to keep Fold Cottage as a two person place, even though smaller places are often advertised as sleeping loads more people when they are little more than bedsits. We like to enjoy a bit of space, as sometimes it rains in the Lake District. Occasionally, it can be tempting just to stay indoors, light the woodburner and read a good book!
You're welcome to bring your dog but it'll have to bring its own bed.
Throughout the downstairs, we've got slate floors with underfloor heating, and there's underfloor heating in the bathroom.
This isn't the best plan in the world but it gives a reasonable idea of the layout.
