You say you have the funds to renovate, but what about set up costs?.
Depending on how many it will sleep you will need to have extra of everything
i.e. bedding - winter and summer duvets per bed,
sheets (lots of), duvet covers, what about protectors for mattress (expensive so wise to cost in at least 3 protectors per bed to save them), pillows and duvet protectors plus spares.
It will have to have plenty of cutlery, crockery, glasses, mugs etc. no one wants to have to wash up after each meal you need a days worth for each person.
Seating will need to be for more than the number sleeping there, no one wants to sit up right squashed on a sofa. Plus extra dining spaces.
Kitchen equipment has to be plentiful.
Then don't forget the constant repair/replace costs, glasses get broken, crockery gets chipped, oven trays/ pans get burnt, bedding gets stained beyond hope.
Also the ware and tare who can go and constantly do the snagging jobs that crop up? it has to be in top condition for every new set of guests.
You will need replacements of stuff close by in a warm dry secure place because there wont be time on the change over days to go shopping for stuff. Remember that you wont have a clue what needs repairing / replacing until you're in there, people don't always let you know.
Guests will happily run up huge bills like having the heating on full when they are out, sometimes leaving lights tv's on etc. (yes it does happen).
People don't always leave or arrive on time cutting down on the change over available time but you can't cut corners.
Don't forget the outside space that's just as important, garden has to be tidy and well presented, garden furniture has to be in good condition. Will there be storage for winter?.
Some people really are hopeless at recycling, they seem to panic when leaving thus putting anything in any bin, that will be a time consuming and a horrible job to sort as it's not fair on the next guests to have no bin space.
