I copied this from an earlier post of mine in response to a similar question. It describes Seton Hall to some extent, but they have pretty much everything you need except clothes, personal toiletry items, and food.
One floor is used for guests and only a few other patients/families were there during our stay. It was by no means an environment with many patients and sick people around to depress you. For us, the convenience of Seton Hall was of most value. Los Angeles traffic can get pretty bad and the neighborhood is not the best (it is safe, just many homeless people), so staying there would allow your family to walk back and forth as needed. There is even an underground walkway that connects the two buildings for added security or the unlikely event of rain. Just keep in mind that Seton Hall is very basic, but clean and has everything you need. The rooms have a queen bed, pull out sofa, flat panel tv, and wifi. Some people on this forum stayed elsewhere after surgery to be in a nicer vacation-like environment, but I wanted the convenience of being next to the hospital just in case something happened. It never did, but am still glad we stayed there. We were able to walk to the hospital cafeteria for some meals. Seton Hall had a kitchen with a microwave that you could heat up food purchased at a nearby grocery store. There weren't too many nearby walkable restaurants, but we had a rental car for the days we wanted to eat or go elsewhere. Seton Hall also had washers/dryers and an unlimited supply of washcloths and towels (self serve), which was great for me after surgery.
Regarding the hospital, there is not really much your husband will need the first day, but once out of ICU he may want some items to take up the time. My wife brought my iPhone and laptop so I could check work and personal emails, make calls, and access the internet. If your husband likes crossword puzzles or similar, those may help. Much of what he does will depend upon how he feels. The hospital room has a tv and they will give him slip resistant socks for walking around and to keep his feet warm. Some people suggest bringing a robe, but I found the temp very comfortable.
I'm not sure if you are going to stay at Seton Hall after your husband's release from the hospital, but if so he'll want to be sure to have comfortable walking shoes. Recovery will consist of a lot of walking and balance exercises.
