Walk to work is unbeatable if you're in finance/legal, and the restaurant scene inside DIFC is excellent. Feels dead on weekends and holidays since it's mostly office crowd during the week
The area has many things to offer all around if you are into luxury, all the high-brow restaurants are here. Fantastic location however there is lots of traffic and it is difficult to find parking. This place is best for bachelors or businessmen who are always on the go, it is not family friendly compared to other areas.
I lived there for about 6 months. It is easily accessible by metro.
