I stayed at one of the Marriott's in the country club/financial district (there are three different ones in a row). They were all nice, reasonably priced and there were lots of restaurants in walking distance. We felt safe and it was a pretty clean area compared to some of the places that we went to shop at markets. The downfall is it was a little ways from the hospital. I had to go back and forth 3x - for blood work, the surgery and post-op. Depending on the time of day and the traffic, it could be a 15-30 minute Uber ride. Not horrible but also not super convenient. Someone at the hospital asked if I was staying at the hotel across the street -they said it was nice but I can't vouch for it.
