RIP OFF and a SCAM
This agency charged us 39 EUR per ticket, which is more than double the official price (18 EUR) for the entrance tickets for Park Güell in Barcelona. The very basic audio guide does not justify such a ridiculous price increase, so basically you are charged for “operational cost and support service”. It uses a cover website that resembles official sites, leading to confusion and overpayment. AVOID at all costs and double check that you are actually on the official site before paying.
