The city space would be smaller than UAE i.e. in Doha, but you will find millions of filipino's here, much more than you can find in Dubai. 

The climate is seriously hot.

Qatar is entirely different from Dubai, But it is a place you will learn to like soon.

Not because of anything but because of nothing. 

And, Try to get a little bit better salary, if you hit Qatar and you don't like the job, you will have to adjust with a 2 year ban, unlike Dubai.

Best Advice I can think of: Come here on visit visa for a month or so and if you like it stay. Take Care.
