Always, I don't know whereabouts you are, but we also found that when we were marketing our rural Wiltshire house in late 2014 that both grand country houses and small cottages were selling whilst the mid-priced houses such as ours were hanging around. We'd already found our onward purchase so were none too pleased when a neighbour suggested the average selling time for the area was twelve months!
Ours went in the market on Sept 1st so still school holidays but we wanted to be in our new house by Christmas so time was if the essence. Our first viewing came the day after we hit RM etc, but then we didn't get another for a week. The first was too good to be true as we had a call from the EA while we were driving home from their office where we'd just approved the draft details......think it was someone on their books that they called up to see if they'd be interested in viewing. That person - an older lady who was downsizing (ours was a 2500 sq ft 5 bed house) - thought it was too dark......yep, it was a thatched, stone built, 200 year old house with typically small windows and low-ish ceilings 
After approximately four weeks we dropped the price - we'd gone with the middle of five EA valuations - which led to a mini flurry of viewings, all of which resulted in offers, one at asking price. Had we not already found the house we wanted to buy we'd most likely have held out at the original price and going by sold prices in the area I think we'd have got close to that but it might have taken six months or more.
Once we were on the market I was in contact with our EA via email every few days discussing how things were going etc, basically reminding them we were there!
One downside we had was our proximity to a rural A road - in fact one EA who specifically targets London second home buyers wouldn't even come out to do a valuation once they knew our location! The EA we did use had a London office, but in the end our buyers were a local family.
I guess it boils down to how much patience you have, whether you are uber keen to move (as we were), if your price is pitched right and if you're targeting the right buyers. Depending on how quickly other houses are selling/your own circs I'd give it another week or two then consider reducing.
