I think I'm the first review so I'll make it long.
The best part for me was the location, it is an artistic and hip area. I'm always cautious as a solo female traveler so I'm generally in before it's too late but there were always tons of interesting people around when I did go in at night. Right outside the door there are coffee shops, cool thrifts stores and architecture. Big transport hub a few steps outside of the home. 10 minute walk to a big mall. 10 minutes in the other direction leads you to a sort of Old Town that goes further into an area that has more bars and restaurants, that seem to always be full. Great place to meet interesting people from all over Turkey and more.
The apartment is great, I recommend. You can tell they put a lot of attention and love into their home. Everything is accurate in the images. It is quiet for sleeping. They do sleep with their door open so I'm not sure if I disturbed them. I sometimes work in different time zones. It is possible to work in the living/dining room during their normal working hours for remote workers. It's an open floor plan.
There are two gorgeous cats, you should be pet friendly. They work right near their apartment so the hosts were always accessible. She has a beauty shop so she can probably give insight into that. We didn't have a common language but we were able to translate fairly well and they were always kind.
