For me a few alert barks in the house is good. Part of the reason we have the dogs we do, is so they guard the house/us. We use "thank you" as the sign that we understand there is a possible threat, and don't feel action is needed. We also reward the dogs for returning to us after the alert bark and a second reward after settling down after an alert bark.
During play and while we're out and about I have different rules for each dog:
Lexi - doesn't bark, so not an issue. If she did bark, I'd take it as a sign from her about her comfort level or something happening.
Rosco: Barks when overstimulated. If he's barking, he's too excited and needs to be redirected into something more positive.
Luna: Barking fool! LOL. Luna barks during play, but she can be rude about it with other dogs and occasionally with people. She mostly does it to Lexi, who will put her in her place and refuse to play with her when she is being a brat. I am fine with Lexi regulating that because they don't escalate and Lexi is very fair about her corrections. If it was a strange dog then I watch that dog very closely to see if Luna's play style is not a good fit.
If Luna barks at me during agilty or while playing chuck-it/other games, then the bark ends the game temporarily. She can be a bossy handful, and her barking at me during play is like saying, "Mom, throw my ball. I said throw my ball. Throw it now! I said throw my ball!" (Hence my not rewarding that behavior by throwing the ball, and my request for her to be polite.) I will turn away, wait until she is quite and calm, turn back and ask for a hand touch to start the game again. I also see this as an exercise for her to learn/practice self-control. She is also young, so her rules may change as she matures, but for now I am trying to raise a wild teenage Aussie! 
Everyone I think has there own idea of what kind/amount of barking is OK. In your situation, I think I would ask my friend not to worry about my dog's barking, but to let me know if she's not comfortable with the play style so you can intervene.
