Inspired by the 'horrible experiences of being a guest' thread!
Obviously we all want houses we visit to be kept at our personal Goldilocks tempetature, but given the choice between staying in a house that felt way too hot or one that felt way too cold I'd go for hot every time.
If it's hot you can open windows in your room, sleep practically naked, or invent a task like emptying the bin to temporarily cool yourself down a bit. But a far too cold house just gets into your bones and it's impossible to warm yourself up once you're freezing, especially as when you're a guest you aren't moving about much.
