i didn't realize that i didn't take the right taxi to the airport until i sat inside. it was too late to change it. However, the taxi driver charged me EUR20 From viru taxi stop to the airport (by meter, but extremely higher price, started at 4.8EUR and 3.2 EUR per km). When I arrived Tallin, I took the advise from hotel reception ((White Tulika taxi or yellow Tallink taxi are the safest ones) ) , the taxi fare was EUR7.8 Be careful to have same mistake I took and be cheated!!
