Hi! Depends on what you're looking for...I know a few students who live in San Juan beach front high-rises and commute about 30min every morning to Caguas, where SJB is located. If you decide to live closer to the hospital/school, you can usually find landlords renting out apts/studios generally in the $350-$600 range. If you don't plan on getting a car (I walk to SJB) live in Bonneville area off of Ave Degetau...it takes me about 10 min to walk. Some students opt for Los Prados which is a nice gated community with a grocery store, Starbucks, Wendy's, etc across the street and about a 5 min drive to SJB without traffic. Hope that helps.
Also, piece of advice...confirm with your clinical coordinator that you are going. Then I would contact Lissette Torres, the Registrar here to make sure that AUA did in fact send your stuff. Imagine my surprise when I confirmed my rotation a week before I left the States and to arrive at registration in Feb to be told that I wasn't on their list. Luckily Ms. Torres was very accommodating and now I'm halfway through I.M. Check out the SJB website for her info coz this site won't allow me to post email addresses. Buenos suerte!
