We don’t supply bed linen because it’s hired in via the agent. Ditto towels. We have M&S beds and mattresses. Decent beds and mattresses are a must with toppers and protectors. Ditto for pillows. All bedrooms have chests of drawers and a mix of built in wardrobes and free standing - all M&S. All beds have high quality bedspreads (for photographs) and cushions. Rugs too as we have limestone floors in part of the house. All bedrooms have side tables and lamps for reading. Two bedrooms have smart TVs. Kit out bathrooms with mirrors.
The dining area has a glass table we had spare. It’s rectangular. The cleaners dislike it but it’s lasted well and no ring marks! Provide place mats. We have coloured “butterfly back” chairs for dining similar to the Christine Keeler one! We have a sideboard from a local shop and various wall art, mirrors and lamps. In the sideboard there is info about the house and the area plus local guide books.
In the lounge we also have leather settees. Big squashy seaside type cushions, an arching lamp and a rug. We have a driftwood style coffee table and it has ring marks on it. Painted might have been better. Latest smart tv and we used to have an iPod dock until they went out of fashion! We have wi fi.
I agree that all kitchen utensils, pans, cooking equipment should be serviceable and decent quality. Buying cheap is false economy. Again, the whole lot from M&S. Cutlery, glasses, plates, chopping boards, knives everything is sturdy and dishwasher safe. All was M&S. We have a kettle, nespresso machine, toaster, food mixer, cafetière, built in microwave, fridge and freezer and dishwasher and washing machine.
Think carefully about window treatments. Guests seem to have problems operating blinds! We have just changed one set of blinds to curtains. Yes to a small plug in vacuum cleaner. Don’t forget dustpan and brush.
Try not to get annoyed when guests break things. I found it incredibly annoying and they don’t always tell anyone. We also provide a picnic set and things disappear regularly. Provide outside seating. Have enough spares of everything!
Good luck.
