What is expat life like in the Algarve?

Hello dear expats, I am just starting to research the place and would like very much if a local/expert could give me some advice regarding the real life, not the touristic life there.
First, let me introduce myself. I am from Bulgaria, Eastern Europe. I am married and very soon we expect our first child. My wife and I are in love with the sea and warm weather and for some time we've thought about relocating for a year and trying a place with good weather all year, nice beaches, normal prices and English-speaking locals.
Could you please let us know what life in Algavre is like for young families with small children? What are the average prices for rentals for a year (not big American style houses, we need just 2 bedrooms and enough space for 2 adults)? What is the weather like (does it get very hot)? Is there good internet (as I need fast and reliable connection for my work)? What are the attractions or activities one can do there? Are there good and affordable kindergartens and schools etc? Please give as much information as you can. This will very much help us decide if it is a good place for us to move as soon as the little guy can travel.

Kind regards, Dilyan
