A pet peeve of mine is the demand for property that has (whatever-country-they-are-in) CHARM - and then, complaining about everything they are shown that even remotely fits that description.
Listen fools, the charm you claim to value usually comes with lots of stairs, small rooms, small yards, no oven, no dishwasher, toilet in a separate space, etc., etc. In other words - it will NOT be what you had in the US and isn't that the whole point?
On the other hand - if they find someplace that is sort of closer to home and they like it; but, aren't sure if they should try it because - you know, they won't get the CHARM??? I have an idea. Take what makes you happy and comfy. Then just know that every time you leave your house, bingo - you're still in the charming foreign place and you can enjoy it all you want. Problem solved.
