As others have said, just get the basics right for me, I don't want too many extras.
King sized beds, cotton bedding washed in fragrance free laundry products, in fact no fragranced stuff anywhere, reed diffusers etc will get moved outside.
Decent furniture, crockery, cutlery, good quality towels. Easy to use appliances and clear instructions for bins etc.
Non-blackout curtains - by all means have separate blackout blinds for those that want them but I get annoyed when the only option is full blackout or open, I hate waking up in the dark in summer.
A pint of milk, tea and coffee, maybe a cake on arrival but no other food and no wine, we are unlikely to drink it. We prefer doing our own shopping.
Definitely no popping in during the week for any reason other than on request for maintenance etc.
A shelf full of books is nice, also maps and guides to the area.
One of the things I like best is finding enough loo roll, dishwasher tabs etc to last the whole week.
Saturday to Saturday rental, Friday is annoying as you have to take an extra day off work.
