It's Hewetson Court, on the bit just off Main Street in Keswick. It's one of several apartments in a courtyard, so it's quiet, but you can walk everywhere. The main shops are about fifty yards away. The private parking space is a big plus, you really won't need your car.
It's a two-bedroom place, sleeps four. One bathroom. There's wood furniture in the bedrooms. It's got a 3 Star rating, so it's comfortable and clean, not luxurious. The double glazing works well, it's quiet inside.
You can walk down to Derwentwater in about ten minutes. The leisure pool is close, and there's a park with tennis and things right there. Every pub, restaurant, and shop you could need is on your doorstep.
For facilities, you've got a washing machine, a dishwasher, WiFi, and a TV. Bedding and towels are included. There's a cot available. No pets, I'm afraid.
If you want to plan walks or days out, these sites are useful: Lake District National Park and National Trust Lake District.
