It looks amazing - good luck with it 


We have a Labrador so would vote for dog friendly accommodation in a cottage,
I know this is too late as you are about to get your 1st guests
The thing is that I am in a wheelchair and so please if you are going to say mobility impaired guests welcome please use a pushchair to go around the whole cottage and the outside
That way you will notice any steps or uneven floors,
If you have any steps measure them and put them in the info you send out to guests, also the heights of sofa, chairs (dining and sitting room ones) also and very important the height of the bed, also bathroom sinks, toilets, kitchen counters etc
The thing is that an able bodied person will say there are no steps inside the ground floor but there are but your brain doesn't notice them you just go up and down them, like kerbs on the roadside, your brain doesn't think "oh there is a kerb I must raise my foot to go up it" it just does it automatically
Also in the shower area get a flooring like ALTRO and also make sure there isn't a step into or out of the shower cubicle or if there is put hand rails to help getting in or out
I know your house is very old and so you can't add things to make it wheelchair friendly but even if it was going to be for a mobility impaired person, little things like small steps are massive and can change a persons holiday, so use a buggy and so you notice if there is a step down into the boot room or kitchen for example
It looks amazing so really hope it goes well
