You can't fault the location of this YHA, it is right beside Windermere lake and my room looked out over it. It is a great starting point for exploring some of the lakes and fells. The room itself is pretty basic, bed and cupboard in a room, but that is the proposition so it was fine. I did find the bed a bit hard. My room was private and had its own toilet and shower, it was all clean and functional. The shared versions looked fine too. Otherwise, the place had a bar/restaurant for food and kitchens available for self catering too.
I used buses to get around as I had no car (stop very nearby). There are buses to most of the nearby popular places, but most of the services are only hourly, so not the easiest to move around fast. Half hourly to Windermere.
Overall, with an understanding of what to expect, I think the place represents good value and the location is great.
