Malachite,
Yes, it is a good place to stay, but keep in mind that they do not do anything physically for you (you mentioned you considered getting a private nurse). Certainly if you need things carried and the like they will help. That said, it is still a great place for a person who comes by themselves because it is not like they are going to leave you hanging out there if you need some help with getting your shirt on, or whatever! Honestly, though, I think you will find that you don't need much in the way of "hands on", help. The surgery really isn't that bad.
The benefits that I see of NBR:
1) Drive you wherever you need to go
2) You won't feel "alone", like one would if they were by themselves in a hotel room
3) If there is something happening with your healing chest that concerns you, the host (who has 30+ years nursing experience), can put your mind at ease and let you know if it is "normal" or not.
4) Huge savings on food because you can cook for yourself. There is always the option for ordering in food, as well.
The recovery wasn't as bad as I thought. My partner is here with me, but really with the above support, things should be smooth for you, even if you have no one with you. You can make sure everything is in place before surgery, such as how your room is set up. They have dressers that are low to the ground, for example, so you don't have to lift your arms. It is small things like that which makes it a good place to stay.
Most people come two days before surgery, and leave either the same day as their post op appointment (6-7 days after surgery), or leave the day after that. My post op appt. is this Wednesday and NBR is driving us right to the airport after my appointment. You might get a little bored if you are here for two weeks.
