Melike and Ahmet are great hosts.
Ahmet helped me check in at 1 AM (!) and provided all of the info needed for a good experience.
The apartment itself is very well equipped and has just about anything one might need. The room is not very big but comfortable. A table is good for those who need to work from home. The cat, Sarmin, and a lot of plants in the living room give a great sense of home to the place.
I totally recommend staying at the place for those who pass Istanbul or come here for a long stay.
