You could always kindly ask the person that contacted you to forward you an email containing all the interview details. Stuff like Company address, time of meeting, location (if you don't get someone to pick you up at the reception), contact point in case of unforseen events (this should also contain a phone number or at least an email) so you can contact them if something shows up and you're late or you can't make it.
You could also ask details about the interviewing process, covered technical knowledge asked at the interview (so maybe you could refresh those areas beforehand).
I've never met an interviewer that flat out refused to provide this information (I mean time, location, contact person) in email form or that was offended by my request.
