In my experience, airport taxis in Rio are a complete con!! The first time my husband and I arrived in Rio we bought tickets from one of the 'proper' taxi desks. However, by the time we actually got into the taxi our little ticket stub,with the price on it, had been crossed out 3 times and the price had increased by R$20!!! While I realise this is not a huge amount of money to those of us travelling from Europe it's still not a great feeling knowing someone is essentially robbing you!
Since this first trip, 3 years ago, we have used Rio Airport Transfer, who offer an unmarked, private taxi service between the international airport and anywhere you want to go in Rio de Janeiro city.
We have found them to be absolutely splendid, their customer service is impeccable, and they typically offer additional travel advice, particularly on hotels and the location of our hotel - very helpful.
I would highly recommend their service.
Regards
Nancy

They're not exactly running a complicated service - you book and pay, and they meet, greet and take you to your hotel - but the process was efficient, the gentleman who emailed us was helpful and it felt good knowing we didn't have to think about how we were going to get to the hotel when we landed.
Worked well for us, would recommend using them if you want a stress free journey.
