Complete rip off and unreliable service.
We have used similar services for our family, and never had experience as poor as with this one. The service is unreliable - no one will try to contact you with any confirmation, and contacting them is nearly impossible.
Furthermore, it is somehow your own fault if you sat on tarmac or up in the air - with airline restrictions on phone usage! - if the driver decided to leave the airport withing an hour from when the flight was scheduled to land ORIGINALLY, that is, at time you had to put in the form during booking.
If your plane did not land on time, they will not wait for you the 60 said minutes, they will be gone.
In this era of information technology, an 80-year old grandma knows how to check if a flight is being delayed BEFORE heading out to pick someone up from the airport. It is crazy to see a supposedly professional service to NOT do this. Unfortunately, we also had a return to airport trip booked with these guys. No matter how we tried, days ahead and spending our on roaming phone fees, we could not get in touch with them to find out what time they will be at our hotel, to make our flight out of Stockholm.
Finally, as we were about to give up and call for a cab, someone called my phone, and said a semi-rude where were you?! Driver did not see you by the hotel!
So we rushed down, and finally got our ride. BTW, nothing Luxury - regular clean-ish van, nothing special for the ridiculous price. We were greeted at our next city airport by a very courteous driver, even with a care package of water and snacks for kids and us, in comparison - a 100% better service and deal than this one.
We got no refund, or acknowledgement of this faux pa by someone who claims to be a serious, professional, and luxury service. We are not luxury and very picky family, but we expect what we pay for to be on the level. This is not, and by far. You will be better off getting ripped off by a local cab driver at the airport, than buy this service. Do not book this.
