Has anyone ever used Transfeero car service in Europe? We're going to be in Austria & Germany this winter, and we're looking into using this service for a day trip between cities. We can definitely get there & back cheaper with a combination train/ bus trip, but our overall schedule is pretty tight so we're considering this as an option. If you have used this service any feedback would be appreciated (or other companies to consider).

I have not used this service but I have used a similar service to get from Berlin to Gdansk called daytrip. Might be another option; it wasn't cheap but got me where I needed to be with stops along the way.

Why not rent a car? Take relying on others out of the equation.

Another vote for Daytrip. I've used multiple times in Europe to "reposition".

I've always felt their fee to be fair and they've always been punctual.
