First of all - I was affraid if that's not a scam. No, it's not.
Secondly - I was affraid if they will come in the time we set. Especially it was around 4 am. They did.
Thirdly - I was affraid in what shape the bus will arrive and if it's going to be able to take me to the airport. He was magnificent and brand new.
I made it to the airport on time we have scheduled. The car was amazing, clean and very new. The driver - one of the nicest I have ever met.
The contact about shuttle was excellent. I knew everything before. The people on help center were very helpful.
I TOTALLY RECOMMEND. Seriously.
Everything was nice. The only thing in my opinion, is nowadays shouldn't be required to print the ticket.
All the best :)
