Difficulty in accessing app. Ticket states it’s been used when I tried to download and wouldn’t let me view it. Xxxxxxxxxx

AWFUL! The confirmation message didn't give any connection that enabled me to use the program. It us totally useless and a competent waste if £9.99. The only way of trying to sort it out was a london phone number where an American speaker was useless and knew nothing of the tour I'll try to get a refund by doubt I'll be successful. I WILL NEVER USE VIATOURS AGAIN

The instructions provided for how to redeem the tour were non-existent and instructions for cancellation were equally vague. I emailed the tour provider for help but it took them 2 days to respond. In the meantime, sensing that I had wasted my money, I spent quite some time trying to work it out for myself and eventually found some info on a forum, which pointed me to downloading the Viator app, so I decided to cancel that way. Would have been useless if I had booked on the day! Very dissatisfied, won’t use again.

Paid for the walking tour, never received the link. Called the out of country help line (not toll free0 and received voice mail.

Absolutely appalling - couldn't even get the code for the tour to access the app. No instructions provided. No help from TripAdvisor despite spending 20 minutes on a call going round in circles with someone who didn't have a clue how to help me. Spoiled a surprise for my mum n dad's pre Christmas present trip to London

Istanbul was an exciting venture. We enjoyed the bazaar and visited the town where they weave the rugs. You get a full tour of the facility where the women weave, by hand, the silk rugs. We bought one and they shipped it home to us. We ate at an amazing outdoor restaurant on the water. And don’t forget to visit Athens!

Directions unclear, and so many missed opportunities for interesting information. 12 places were chosen, and too much and too boring information was given just on those. Chatty banter between two narrators was just annoying. I think this tour must have been cut & paste in 15 minutes. There’s so much history to every street in London- there’s no excuse for this.

This is a nice way to spend some time soaking up the sunlight if the weather is good. The punters are sometimes amusing to watch. So if you want a short break from a meeting or from the town it is a good thing to do.

Very misleading, looks like a real tour, the title says walking tour with a date, availability check and meeting point. :) In the end it turns out it's just the PDF/video for the self guided tour. Way too expensive for what it is. On top of that they would not refund when I realized the trap.

Very dissatisfied. We booked a walking tour and we got PDF files. Of course it is a scam. They mislead people, take their money and then they can't cancel the tickets.

Not good at all. Although the commentary/guides was very informative it was spoilt by lack of instructions on direction. Several times I had to pause the tour and google search the next point location as the map with the App was pointless ... it pointed to a route that didn't have location points of the tour and didn't match the site. The App also seemed to distort several times when walking so I had to constantly restart. overall the guide has good potential with refining but for now it was unsatisfactory and a waste of money.

Amazing the place is really nice, the main holiday recommendation, I took lots of photos there, in fact I still think about it and want to go back there againview!! I took many photos in there

Kate was an excellent tour guide, informative, knowledgeable and helpful. We visited many of the key attractions of Stratford on the tour. Well worth it.

A stunning oasis of calm and nature in this very densely packed city. Above the street level the noise disappears and all around is planting, trees and birds - and the occasional rusty railway line. Get some close-ups of the eccentric architecture of people or corporations with more money than sense. En route you can stop off at the buildout into the Hudson River, and take in the views of Jersey City, drop down to the street to visit densely packed shopping arcades for a bite to eat or cup of coffee.

Unable to download tour -I managed to download mine but no one else could. Took the tour and it was informative and engaging but had to quit 1/2 way through - legs got tired but I’d been walking previously.
