Port Loca Karaköy

Very comfortable for work. Calm environment, stable WiFi on all floors, lots of outlets, comfy chairs and sofas, variety in seating so you can pick what's most comfortable for you. Third floor lounge (20 TL extra) was great for work - you have your own secluded spacious area and a phone if you want to order something from downstairs. Can work while having a variety of drinks and shisha. They also offer full meals, also lots of variety, that were delicious. I was able to stay for as long as I wanted, no restrictions.
