We (husband and I) are IT professionals based in Singapore. We love to travel, and like to get a real taste of the local flavor of a place rather than to check things off a list of tourist attractions. Our best travel memories are from trips where we've rented a place from a local.. it feels a little like being home while away. Plus, what better way to find out about a place than getting to meet someone who lives there!
We haven't hosted anybody so far (one day!) but if we did, we'd expect our guest(s) to treat our place with the care that their own home deserves - so we do the same when we are guests.
