Pretty active WhatsApp group for digital nomads. The quickest way to find your community in Antalya. Organizing weekly coffee meetups, you can find it in the group description. Other activities are shared by the members as well.
Octopus is a nice bookshop next to Kaleiçi with a coffee shop and workspace on the ground floor and a partially open rooftop café which is popular with students doing homework. Be aware: Octopus kind of doubles as a cat cafe...
Unique combination of bookstore-bikeshop-restaurant-coffeeshop which is popular to work from. It's part of Akra hotels (across the street) that also has a nice lounge to work from. The 251 Soul Bar is Antalya's best jazz club with lots of live performances and a monthly Social Sunday around the pool area.
Veruna is a popular chain in Turkey dedicated to globetrotters. Nice all-day breakfast, extensive international menu incl. Pad Thai, sockets at most tables and several tables are a bit secluded which makes Veruna even suitable for an occasional (video-)call.
Not as optimized for working as some of the other coffeeshops at the beach parc. But it's popular because it's closer to the sea. Also there's a glass booth, suitable for having semi-private calls.
