This company is probably a registered business but I found them difficult and elusive to deal with . Months ago I booked a tour of Paris catacombs and seine tour . They issued a voucher which had scant details .No ticket just a meeting point at entrance of Catacombs where the voucher said tickets would be issued. Arrived at correct time only to be told this voucher was not sufficient. Went online to viatour and lot of back and forth finally got a ticket . I think this company operates on making things difficult. They already have your money and if you don't show up don't have to pass it on to the operator . Some people would give up and write it off. I suggest avoid this company, go direct to tour operator
