Dorms are allright. Most are not equipped with A/C but they do have heaters. Not a problem for me, since Long Beach is pretty cool weather compared to my hometown. There are double rooms and few single rooms (for upperclassmen). They have something called a Residential Learning College, which is a community college one mile away from CSULB that they renovated into dorms for students. It's more of an apartment-like experience I suppose.
Reputation - it has an amazing nursing program. It's also very well known for fine/performing arts. Many arts majors are impacted. It's the 2nd largest public school in California and also the cheapest CSU in the system, I believe.
The very immediate area around CSULB is pretty quiet - the suburbs. Not sure about internships, but CSULB students get access to an online forum sort of place where local employers and businesses post job/internship opportunities. There are quite a few. If you go a little bit away from CSULB, you get to places like Compton where it's... a bit scary haha. But as long as you don't go there it's all good. It's a nice neighborhood, not too far from Irvine/LA/etc.
I have no idea about int'l studies reputation.

sorry
Professors are great, in my opinion. They're not really here for research like the UC professors are, and the bunch of them are very caring about the students, willing to engage in conversations with them, and actually teach the classes... of course there may be one in the bunch that aren't as great, but that's the same for all other colleges, no?
CSUs have a GREAT study abroad system: click here

The nearest beach is 3 miles away. As for transportation, there is a bus that takes you to the beach

and I believe you can use your CSULB student ID to get on the Long Beach buses for free. There are also metros and all that good stuff. The Long Beach airport is very close as well (planes touch down constantly).
Hope this helped!
