Hi, Sarah. We've stayed at Hotel de la Sorbonne in the Latin Quarter and the location is absolutely perfect. It is 60 euros a night and has a 5 euro breakfast that is a bit better than the typical "continental" breakfast. They have 24 hour desk service; most seemed to speak English if that's a concern; you'll have a private bath; the place is very clean and the area is not only very safe, but it is within walking distance of most of the major tourist sites. It is also an easy walk to two or three Metro stations and two RER stations although I've been told the St. Michel RER is closed for the summer. They are doing renovations and I don't know when it will reopen. The Cluny and Luxembourg are probably closer anyway.
You can find the hotel by clicking on the blue and red france.com above. This will take you to the home page. Scroll over to the right and find the hotel search box. Scroll down to the Latin Quarter and then click on the Search button. (You can also type Sorbonne into the search window at the top left of your screen.) We book through France.com all the time and have never had any problems with it.
If you don't want to pay 60 euros (which is a very good price for Paris), you can also click on the blue and red france.com at the top of this page to go to the Home Page. Once there, again scroll right and you will see a list of words, i.e. Hostels, Airfares, Rail Travel and others. Click on the top one which is Hostels. This takes you to a selection of hostels and very inexpensive hotels. We haven't used any of these so I can't personally recommend them, but it will give you an idea of what is available and the cost. Then you can go to a site like Virtual Tourist or Trip Advisor and get reviews to see if you want to try a hostel. I've seen some highly recommended on other forums so it might be worth a try. Just be sure you are in an area close to a Metro and that should be pretty easy.
