We used hostelsclub.com to book accommodation in Rio de Janeiro for carnival. Knowing that this time is very busy and expensive we booked in August 2010 for March 2011! We tried to confirm our booking with the hostel in Jan but they never replied to the 3 emails I sent. They did however manage to email us 1 week before we were due to arrive to tell us that hostels club made an error with overbooking and we couldn’t get the private room we had booked and that we would have to share. Hostelsclub did not to reply to another 3/4 emails I sent!! I doubt this was a hostelsclub error, since it turned out to be a hostel scam after we were put into a dorm with 10 people and they refused to budge on the price. BUt they could have replied – it was a very stressful time for us and the stay here has been horrible.
