@tanjaostman we may well not be the norm for the UK. Some people can be almost rude about you arriving at their house, and the need to remove your sirs before you're allowed to come in
Cold feet is the one thing I've always been susceptible to, and I don't like others getting cold feet.- under floor heating is certainly no common in the UK
@Cherishingsparrows2020 makes some great points
Personal I'd prefer slippers over shoes in the houses, but they're so expensive.
Hardwood floors downstairs and carpets upstajrs is my preference (not that we get any say with renting houses)
