If you are coming to a conference or anything attached to the convention center, you are in luck as far as logistics. 10 minutes down flamingo and your are at the Venetian where I always park in their park garage for free. Works well.
The patio at Alexis's has a charming fountain which is subtle, and pleasant. Hummingbird feeders and flowers accent. Safe appearing neighborhood. No traffic sounds. Very tidy all over.
