You have raised a very good and important issue here in Doha. I am also finding an accomodation here and has visited many accomdoations here after i bought my car and got my license. Without vehicle you cannot move around and have the accomodation or cant have good food here. Taxi is rare in many parts of Doha.

Usually what is mentioned in the ads is not there once you go and see the accomodation yourself.

Only the agents getting some money from you can find you the accomodation if any.
