The only vaguely difficult thing I remember about it (after just one visit, daytime, in good VMC I should add) is that the runway has a 1.8% slope on it. My airfield guide (a few years out of date, since it's a few years since I was there) has the annotation "Nrmlly lnd rwy 3, tkff rwy 21 xcpt with S wind abv 10 kts." Since the airfield is moderately busy (not the busiest airfield around, but not absolutely dead either), this means there's a reasonable chance that as you arrive you'll meet traffic going the other way, or vice versa.
Having said that, I certainly didn't have any trouble there. I think I had a little over 100 hours when I went there. I barely noticed the slope, and talked over the r/t to traffic going the other way to ensure that there was no risk. It was only after I visited that I heard, third hand, of other schools who wouldn't let PPL hirers go there.
I wouldn't like to speculate on exactly why this is, but I agree with you 100% that it seems a little over-cautious. Personally, if a pilot wasn't capable enough to handle this field, I wouldn't think them capable enough to hire my aircraft in the first place. But if you are hiring aircraft from someone, you are obliged to follow their rules.
