Why booking.com dosent have this logical option for searching suitable apartment ?!?
Let's say I want to rent a three-bedroom apartment for three people. The only option offered is to check the apartment box and start searching. So now I have hundreds of non-suitable apartments (studio, one or two bedroom) displeyed. That makes guests hard to choose between few three bedroom offered amoung hundreds of non suitable.
I think you should make search box under apartment search box : X-one bederoom; X- two bedroom; ...
I am surprised you dont have that option already since there is a significant percentage of the apartments on your site.
