Lived in Rimal 4 for a few years, and found it very convenient. I work from home, so some traffic in the morning was not an issue for me. Rimal 4 is located right in the middle of JBR. There are many coffee shops around to have a meeting. The beach access is very convenient as I am a swimmer. There is an All Day store right downstairs, and a Carrefour very close at the plaza level, so you do not really need a car unless you go somewhere else. Walking on the beach, Marina or Bluewaters any time you want is good too.
