Thrifty - Thrift at FRA - pls. post experience here

Will be in Frankfurt next week and was able to get a good rate from Thrifty. Checking to see what sort of experiences others have had at this location.

I am not interested in paying any 'hidden' charges but I do not have an issue paying what I agreed upon.

I am getting a GPS to get around, does that work well in FRA area.

Thanks in advance for your help.
