My places are a bit like a jumble sale, but as others have said, quality pays. My crockery is a mixture of the porcelain from Ikea which is actually very durable for the price and the French Pillyvuit used by many restaurants. Been to the factory outlet twice to stock up.
For wine, beer, snaps, cognac glasses I go for the nice ones from the hypermarket or the nice ones from Ikea. Easily replaceable without breaking the bank. Guest on holiday do break glasses. Cutlery is the nicest stainless steel ones from the hypermarket. For stainless steel pots and pans, I find the medium range from Ikea to be more than adequate. My non-stick are in the luxury range because I hate to throw away things afer a year of use. It is so wasteful.
To protect the mattresses and add comfort, I use memory foam mattress toppers with washable cover, protect with waterproof mattress protecter. So far, so good.
The TV is mounted to the wall.
Any lamps that are not mounted to the wall have unbreakable bases and I try to avoid floor lamps as they tend to topple over.
Solid wood furniture - they can take a sanding or be painted if necessary.
Tiled kitchen worktops and tiled floors.
Making appliances last is the biggest challenge as they are often programmed to die after a certain amount of time. I am on the third washing machine, second dishwasher, second drier and third fridge in 12 years.
It helps a lot if the host team can act as general handyman, seamstress, upholsterer, interior decorator and gardener as there is quite a bit of maintenance to keep a property in top condition at any time.
