Dubai Marina and JBR's comparatively fresh neighborhood is the city's most Westernized region, virtually the only correctly walkable part of the new Dubai and, in my view, the best location to live in Dubai.
JBR relates to the beach, the walkway and all the first line houses. The Marina, including the tallest skyscrapers and the canal, is all behind.
Most European expats choose to stay here because it's the simplest location to reside in, with plenty of bar choices and no rigid limitations, like, for instance, the way females dress at the beach.
Why you should remain here: if you want to be where the fun is, you should remain here. There's the beach, lots of restaurants and bars, and it's really very spectacular with the canal and all the skyscrapers. It's very well linked to the subway as well.
Al Barsha is Dubai's functional district.
It's not a very attractive location, on the one side. Tourists don't have much to do here, apart from walking around the Emirates Mall (the second most popular mall) to see the Ski Resort.
However, on the other side, there are quite a few expats residing here, basically because it's very well connected to the subway, it's close to both Marina and Downtown and you can save a few hundred bucks in rent a month.
It also has everything you might need, from a Carrefour to many kinds of stores and some really excellent local restaurants, from Arabic to excellent Indians and Pakistanis, so Al-Barsha is a wonderful place to stay.
Downtown is Dubai as seen on TV and the best place to live in Dubai for many individuals.
Downtown, with some of the highest skyscrapers, including the Burj Khalifa, the most luxurious stores, fancy boulevards, and the most glamorous clubs and fine dining restaurants, is why Dubai is popular.
Whether you want to go to the top of Burj Khalifa, shop at the biggest mall in the world, or just check out the fountain display, all visitors come here during their journey at some stage.
However, the region is the costliest in the town, but today more individuals can afford to remain here thanks to the advent of some small, comparatively inexpensive housing.
Bur Dubai is Dubai's Old City core.
Bur Dubai is the true soul of the town, a place that has been inhabited for millennia, composed of tight alleys, true bazaars and traditional architecture.
Mostly inhabited by Indians (and since it was established it has been like that), this is a place to lastly experience some real culture.
Bur Dubai also provides the cheapest prices when it comes to housing if you want to choose which region to remain in Dubai depending on cost. It also has some of the city's most genuine and inexpensive Indian restaurants.
