80 euros is disgusting..
Call G7.. ive used them before , they have english speaking operators.. The taxi will arrive with some money on the meter.. but not much.. and mention it is for five .. they will send a van taxi.
You can contact them by phone or look at website and see if they will give you a cost estimate.
Keep in mind it only costs 50-55 euros to go to the airport.. which is almost an hour away.. thats a preset price for taxis.. but even before the price was set I never paid more than 60 euros or so to come into city.. 80 euros is really disgusting...but they prey on nervous travelers who just want convenience I guess..
Call or contact G7
