This is the Rosthwaite Annexe in Windermere. It's a detached cottage for two people, just off the main road.
It's got one bedroom, which is up a set of stairs and looks down over the living area. The bed is a kingsize. There's one bathroom with a shower. The living space is all open plan. It's got a 3 Star rating, so it's clean and has what you need.
You can walk into Windermere town centre in a few minutes. All the pubs and restaurants are there. Bowness is about a mile down the hill if you want to go to the lake.
For things to do, you're right in the middle of it. The Lake District National Park website has walking routes. The World of Beatrix Potter is in Bowness if that's your sort of thing. You can get to Grasmere, Ambleside, and Coniston all within half an hour by car.
Facilities: there's a washing machine, WiFi, a TV, and parking right outside. The garden is a patio area. It is wheelchair accessible at the entrance. You can bring one dog.
