Seems to me your thread title is likely to be of most interest to people who like walking on holiday. People who don't are probably going to think 'meh' and move on, so I suspect you're likely to get a bias towards walkers.
FWIW I like walking on holiday and would always go for a rural environment, but the right house with lovely gardens could swing me even if there weren't sylvan loveliness right on the doorstep (actually it has done in the past, particularly when the kids were tiny and largely house-bound). But it doesn't have to be an AONB, just pleasant and quiet and safe and, as I say, rural.
A lot of people will want a pub/bar/restaurant and a shop in walking distance. How far is this walk to the village? You say 5 mins drive which could mean anything up to 45 mins, but is there a shortcut that avoids noisy main roads etc? I'm thinking of emergency wine excursions in the afternoon / evening, but also first-thing-in-the-morning strolls for croissants or whatever.
Agreed with PP re. hot-tub, you'll get loads of bookings off the back of it, but they're a swine to maintain (especially when people do ... y'know ... in them) and (I presume) ruinously expensive to run. The pool would only tempt me if the climate was really really hot in your area (unless it's indoor and heated, then I'm yours).
45 mins * 2 every time you want to get somewhere and back is a lot of driving with car-sick toddlers. Assuming people book using a map viewer of properties (eg tripadvisor) then those types of families won't even look at you.
I guess the key is to work out what type of holiday your place might provide, and then optimise it for that. Who do you want staying? -
- Dog walkers? (will want a walk)
- Families with young kids? (no walk np)
- Families with older kids? (will want walk / bike ride)
- Hen parties? (no walk np mostly)
- Culture vultures? (50/50 walkers)
- Retirees? (60/40 walkers maybe?)
- 40th birthday celebrators? (may want a walk to clear the hangover)
etc
Don't know if any of that helps!
