As a travel nurse, the facility/unit/location in which we work changes, so your recruiter and company availability is always of the upmost importance (side note: I have to give a big shout-out to my recruiter, Killian Serrano, and would recommend her to any new travel nurses).
My current contract is the first in which I have had company-arranged housing, and I am very pleased. The housing department set me up with all the specifications I asked for; although, I don't generally ask for much (I asked for a place by the water, and they put me across the street from the bay-- perfect location!).
This is also based on my personal experience with AMN, but I have not had to talk to anyone other than my recruiter about anything-- everything has been taken care of for me. It feels like I have a personal assistant at times, which is kinda awesome. Again, this may be specific to my recruiter.
AMN also has a comprehensive and useful online portal for their travel nurses, which definitely comes in handy. The online portal allows you to submit any HR/Payroll documentation, get some free CEU's, review benefits, search open travel assignments, and a bunch of other things.
Another benefit to AMN is their large network. In addition to contracts available through AMN's website (americanmobile.com), your profile can also carry over to OnwardHealthCare.com (primarily short-term contracts, 2-8 weeks in length) and NurseFinders.com (a per diem staffing agency with offices throughout the country).
