Singapore Expats

Hey All,
I m planning to travel to Spain somewhere in September. And now i need to do hotel reservations online. Any suggestions on which website is reliable and offers good rate? i have found some websites on net but not sure if they are reliable coz have to enter credit card number and a bit skeptical when it comes to doing anything online. So will be very helpful if someone can suggest a good site.

Many thanks in advance.

try expedia.com or trip advisor ....... cant beat them ...as for safety, i have tried them many times, no issues..cheers

Asiarooms is quite good....found that to be the cheapest so far..
