Excellent base for the Hadrian's Wall walk. My wife and her friend walked the wall, I dropped them off and picked them up at the start and end of each leg.
A minor negative, the fridge wasn't big enough for the three of us (the cottage can accommodate 8!), but I had plenty of time to do the food shopping on a daily basis.
Otherwise, we had an enjoyable stay, welcomed by the hostess on the first day and she sorted out any minor niggles during the week (i.e., the DVD player was broken, and she replaced that the following day).
