Try shops near the Qatar Palace Hotel. The road going towards Arab Bank Roundabout. There are lots of shops over there for Carpets & Curtains.

Also try the Carpet Center in Mansoura.

You can give them measurements or They will first come to your place take the measurements and then they will come and install the carpets.

Since you have only one room they will be able to install it in max one hour.

@Radius never by used ones since it will cause health problems for you and your family!!
