I was a rather unsociable guest, arriving in the wee small hours on a late flight and leaving before Dave got up. However, I felt very welcome and was delighted with the location and value. Dave's house is a treasure trove of British alternative / pop culture memorabilia and had I had more time, I would have loved to have discussed our shared tastes in comics, music and films. All in all, thoroughly recommended.
Note for future guests: the fastest walking route from Manchester Airport goes through a park and the path is unlit at night. I didn't have any problems, but if you're easily spooked and arriving at night, you might want to plan a different route!
