Stay in Dilara's apartment was great! Apartment had everything I needed, it was clean and had perfect location for me. Its located just few minutes away from restaurant/boutique area of beşiktaş, has a bunch of cafés around and in 10 minute walk there're bunch of bars/pubs. I would highly recommend this place!
The only thing that was bothering me: lack of plug sockets. There's a table where one could work but unfortunately there's nowhere to plug in a laptop unless you have a long cable.
