I'm 6 weeks out from Oct. 2 2014 translab at House/St Vincents and doing great! No complications, and I was essentially back about my life after 4 weeks post surgery, back to work, driving, etc. All my thanks and my great result, in my opinion, go to my fantastic House surgeons, Dr.s Slattery and Schwarz, as well as Dr Stephan and the St Vincents staff. Your daughter is in fantastic hands - she can just relax! I chose the House team over local/east-coast options (I live near Philadelphia, PA) because of their extensive AN experience.
I was in St Vincents for 3.5 days. I found the staff to be awesome - attentive, professional, and very caring (e.g., I got a sponge bath from my ICU nurse ("Beanie") the night after my surgery - made me feel so good!)
The food delivered to my hospital room however was just ok. Hopefully they can prepare something acceptable for your daughter. My wife would go to the St Vincents cafeteria (in the lower level of the bldg.) and make us a big fresh salad that she would bring to my room, that we would share.
There are not many healthy (IMO...) restaurant/eating options right around St vincents hospital. My wife (and I, once I was discharged and back up on my feet and stable...) liked going on food/meal runs to the Whole Foods ("Fairfax" store) and the "farmers market" across the street from the Whole Foods (~15 min west of the hospital on W 3rd St). There should be good vegan options there! Traffic was interesting during rush hours, but at other times not so bad.
My wife and I stayed at Seton for the ~14 days we were in LA. We found it to be extremely convenient to House and the hospital (even after discharge when I was pretty wobbly on my feet for a week), very affordable, very quiet (hardly any other guests/patients), clean and comfortable. They can provide you with a shower seat/chair - just ask. We had a 3rd floor room, and the 3rd floor has a nice kitchen and sitting area. We could also get reception from our room to the free wifi. There is a beautiful little flower/sitting garden off of the Seton lobby - we would picnic there. Also, once while practicing stairs, we discovered that the SE corner exterior stairwell of Seton takes you all the way up and out onto the roof of the building (just bring your keys). So we went up on the Seton roof (has high bordering walls (not dangerous, IMO)) an evening or two to watch the sunset over the city and take in the "Hollywood" sign on the nearby mountains!
Best of luck to your daughter and yourself! In the near distant future you will both very likely be back about life wondering what all the worry was about. Take care, Keith
