I'm a mechanical engineer. I love sports (I've been doing Track and Field for more than 10 years), watching movies and travelling.
Usually I prefer to rent a flat instead of booking an hotel because I can cook by myself, so I needn't to eat out (it's possible to save up a lot of money). Moreover rent a flat or a room is cheaper than book a room in an hotel :D.
When I travel I prefer to enjoy the city, so I hardly stay at home/room for more than a couple of hours.
