We have used Viator for two of our big holidays thus far and our experience has been very positive. Sadly, however, our most recent holiday did not get off to the best start as a result of a Viator booking. After a two hour delay in immigration upon arrival at San Francisco we purchased a US SIM and proceeded to phone the private vehicle transfer company as per the voucher booking instructions only to find they had left without us. This transfer had been booked and paid for, at time of booking were were asked to include flight details and arrival time. The long delay in immigration, however, was beyond our control. After 26 hours of travel we were understandably upset at having paid for a transfer that was not there waiting for us as expected and consequently having to organise a metered taxi as alternative transportation. I strongly feel that the supplying company should give more detailed instructions to ensure that other Viator customers do not end up in the same predicament. Thus far, as previously mentioned, apart from this disappointing experience, all our other Viator bookings have been fabulous.

Traveled in comfort and style in a spacious black SUV that felt like I was sitting in business class. Easy to fetch. Once you exit, call number, and wait 5-10 minutes on the curb. Great way to travel on our first day in San Francisco.

excellent service ,great informative driver .Very punctual .

Good service and convenient for travelers with lots of luggage. The car was somewhat old and air freshener too strong

Excellent service.

Pick up from airport was very smooth and driver was lovely. However, when returning to airport we were on the phone to the company arranging transfer for over 30 minutes (cost 60 for phone call) and she changed the price three times. We asked her to cancel in the end. She was unhelpful, do not use!

You can now do better with Uber or Lyfft.

The call centre person was quite rude and very defensive.

Very easy. The car arrived in good time and it was all very simple.

Our driver was Mauricio he picked us up at the airport and drove us the hotel. He was very helpful and polite. He offered us water free of charge which we accepted. We talked to Mauricio about what is happening in San Francisco. He was a very pleasant to talk to and a competent driver. I would use Viator again.
