The Atlanta Ikea is next to Atlantic Station at 441 16th St NW. The closest MARTA station is the Arts Center MARTA station on the red/gold rail line. Although the store isn’t in walking distance, a free shuttle regularly departs from the station. Combined with delivery service, shop all you want and have your items shipped if you’re commuting via transit.
At the Arts Center station, go up two levels from the train platform, following the signs pointing to the buses and either board bus 37 or the free Atlantic Station shuttle. Both stop at or near Ikea. It is free to transfer from train to bus.
