I stay at AirBNBs a lot, both in the UK and overseas. Wifi is essential. Less bothered about TV but if you're going to have one, please make sure it's a reasonably modern one. I wouldn't stay somewhere that was just a dumping ground for the owner's old stuff (so no old TVs, no old kettles and toasters, no old cups and plates, no old bedding). A lot of places seem to have been fitted out with most kitchen stuff from Ikea (which is fine).
I would never consider staying somewhere that didn't provide bedding (white) and towels (for bath/shower and also for the kitchen!) Decent quality bedding makes a big difference.
It makes life much easier when there is washing up liquid, a washing up brush, tea towel etc. Plus some salt and pepper, and some olive oil preferably. And of course hand wash and toilet roll.
I've stayed in a couple of places that didn't have microwaves. If you're working, this can be annoying. If you're on holiday with time to spare, it's fine. Please make sure you provide oven gloves if you expect people to use the oven.
I stayed somewhere in Dec that didn't provide a corkscrew. Now that was annoying! (although I suspect a previous guest had taken it as I've stayed in other properties with the same owner and a corkscrew is provided).
Everywhere I've stayed in the UK has provided some form of welcome pack. As a minimum, there's been tea, coffee, sugar and milk. Most leave a bottle of wine. Sometimes there are eggs, bread, butter, muesli, cake, biscuits, crisps, marmalade, sparkling water, it can be impressive. The basics really help.
