Bathtubs are rare (in my experience) most apartments have showers but no tub.

If you are traveling in a city, take the public transit. It is very efficient and runs frequently.

Learn to enjoy real coffee. Swedich (European) coffee is much better than what is typical for North American's to be drinking.

If you get to the Goteborg region, stop in at Liseberg ammusement park. Over the Yule season, they are having an Ice Bar with wine serverd in glasses made from Ice. Unfortunatly I won't be there until next year. :-(

_{disclaimer; My experience with Sweden is in Goteborg and Stockholm, so things like transit may vary where you are.}
