Aponia is such a unique place to see even for local people of Istanbul. I've visited the shop at…read moredown Galata and it was a great experience to meet all that designs on all products! They're also selling some special brand coffee that causes the place to have an intimate ambiance. Tshirts, wallets, postcards, boxes, american services... You may find many unusual gifts. The prices are not so expensive when you compare to have a special design products from somewhere else. Tshirts are around 45 tl. You may meet an unexpected guest inside, a lovely, big, brown cat. :)
