Well, as of our experience, Doha is the WORST place for Todds and kids.
First of all, there aren't many playgrounds only couple but they are always so crowded and the kids are so agressive you don't even want your kid to go near them, the kids here have no respect and no manner, beside it gets super HOT in summer so even forget about the parks.
For sure its better to live in a Villa. I would not recommend living here unless you make some good money to save for your future.
