We stayed at Birch cottage for 2 weeks and had a great time. The cottage is perfectly placed for walking into Whinlatter area and onto Grisdale, Hopegill Head etc.
The view up onto Skiddaw from the cottage is great, watching the changing weather is all part of staying in the lakes. We watched red squirrels in the village and also in the forest behind. Many of the forest tracks are easy walking and allow you to gain height and views quickly without having to be super fit.
The cottage is warm, well equipped and dog friendly which is great. The most important points are that the bed and settee are comfortable, we really enjoyed our stay.
The Pheasent, Crossthwaite Road, Keswick does great food, we had to book, it was very busy at the weekend.
Booths Keswick does a wonderful cooked breakfast, but look out for the full breakfast, it is huge.
The Cottage in the Woods does great fine dining but if your budget doesn't go that far try Middle... Plus
