Most hostel websites will give some sort of percentage ranking or 1-10 rating which should be a good indication as to the weight of opinion. I also check to see comments like "good party place" and I stay away from those! ;) Usually, I find those that have a low ranking for hostal "excitement" are usually quieter places to stay.
You may also want to consider inexpensive hotels. For a smaller sized dorm room in Paris, you'll probably pay 20-25 Euro per person. That'll be 140-175 Euro for all of you, per night. For 150 Euro/night (22 Euro/night/person), you could book three rooms at Accor's Etap hotel in north Paris. It's about a 20 minute Metro ride to the center of the city, but you'd have a nice hotel to come back to, with en-suite bathrooms. We've stayed in apartments in this area, and have found it to be a great place to stay. Another option would be Accor's slightly-higher standard Ibis hotel near Gare du Nord....closer to the center of the city, for about 195 Euro/night for three rooms (about 28 Euro pp, per night.) You are allowed 3 adults in each room, so you could even invite another couple of friends along, which would help reduce per person prices.
