Oct 23: My experience was 5 stars. Got a great car for a competitive price online. On the day, I dealt with Bruno, he was very helpful, knowledgeable, and friendly. Had a week long hire of Seat Arona and had zero issues collecting or returning. I've hired cars lots in Portugal but this was my first time in Aveiro and I'd happily hire a car at Sixt again. (Useful info : its located on the edge of the town centre, about a 20 mins walk or 5 mins taxi from the train station... reception office is on the first floor, just walk up the ramp... )
