People who are looking for a villa for rent that has 3 bedrooms are often a small family with perhaps 2 or 3 children. Around 90% of the 3 bedroom homes (also called 3 bhk) in Qatar are actually apartments. But these are often located inside towers and aren't always suitable for families. Many families instead prefer a villa which might have a garden, like a more traditional house.
If you're looking for a 3 bedroom house then most of your options will likely be compound villas located in Ain Khaled, Al Waab, Abu Hamour and Al Thumama. A compound villa can be better than a more traditional standalone villa, as compound villas often have many additional benefits such as security, maintenance, swimming pool, gym, clubhouse with various facilities, children's play area and other sporting facilities to name a few. Some compounds are gated and others have the convenience of a mini supermarket for groceries, a restaurant or even a mosque. This is what makes them the perfect choice for smaller families!
