Facilities in Barwa ?

If you mean barwa city, it's good, all available except swimming pool.
You have LULU 2 stores, one for groceries, one for electronics,
Junk food like KFC, Papa Jones, Mackdonalds, some restaurants in the second floor in lulu
Starbucks there too, a lot of green areas,
People comes from everywhere on Friday to BBQ, you have newton schools also (4 schools, 2 British, 2 international) 
Minor traffic, at certain times (schools times since you have 4 schools, and on Fridays everybody in al wakra comes to lulu) close to medical centers, closest one beside religions complex
Nice for kids, but it's far from Doha,
Rent is a little over rated
