I booked a room here via hostels.com. I then emailed the Castlegate directly to ask about the cost of parking, and they informed me that they were sold out for the dates I booked. After telling them that my reservation with Hostels.com was confirmed, they told me I would have to request a refund, as they would not honour my reservation. Since then, the Castlegate has done nothing to back up my request for a refund from Hostels.com, and even days after I was told my reservation would not be honoured, the dates were still showing as "available" online.
I normally wouldn't give a negative review for a customer-service related issue, but this is a situation that could have been prevented; the Castlegate should be informing the online sites to block reservations when they are full. And at the very least, they should be helping to make sure I get refunded, as this "error" was not from anything I did.
Based on my experience, I don't recommend the Castlegate, and I advise against booking anything through Hostels.com.More
