2 bedrooms Apartments for sale in Al Juffair - 2 BHK Flats for sale | Property Finder Bahrain quick search on Juffair (one of the most urban areas), 50k are enough for a modern 1br or a little older 2br/110 sqm, but you can have fun with propertyfinder, I will leave you a little impression of the areas:
Juffair: Full of buildings urban area with quite a lot of cheap restaurants, shops, malls and clubs.
Bahrain Bay: Extreme Luxury area, where is the Four Seasons residences, Roberto Cavalli etc.. Expensive but not that much, under heavy development.
Seef: Good and relatively cheap area, close to the previously metioned areas, near to the City Centre mall.
Reef: Kinda like the palm in Dubai, private developed Island with security at the entrance, full of well maintained gardens, expensive restaurants.
Marassi: another island, far from the center, all beachfront buildinds, including The Address.
I think depends on many things: source of funds, personal preferences etc.. personally I much prefer hot weather and no bureaucracy headaches. In CH right now it's 0 C°, here is 20 C° and I'm going around in shorts and t-shirts
