Been living in Evaristo Morales part-time for the past two years. It's adjacent to Piantini, and I'd say that if you want your pick of restaurants, shopping and other amenities, this is the place to be. Piantini is nicer and safer than EM, but that comes at a price. If it's outside of your budget, try to get as close as you can, but be forewarned, traffic is a hellish nightmare in this part of town. Looking at a map will give you no indication whatsoever of how easy it will be to get to where you want to go. It has taken me 20 minutes to travel just a few blocks.
