Stayed a month on Gul's studio. Is one of the best places I've stayed on Istanbul!
Place: this flat has so much character. The paintings really make it look alive, it doesn't have the corporate vibe most Airbnb's have. The bedroom and living room are more spacious than they seem on the pictures too. It was super clean upon arrival too.
Location: the best. Less than 3 minutes walking to Osmanbey metro station. It's a vibrant and neighborhood. Had no problem walking alone past midnight. Many supermarkets, cafes, restaurants, pharmacies and everything you'd need. Its on the first floor so its only one set of stairs. Its really calm by day and night.
Internet: it was alright. I work remotely and didn't have much problems.
Stuff: All the basic supplies were there. There was even a video beam and a curtain for watching movies, which made it even more awesome.
Host: Gul was really nice and flexible about check-in/out. She was always available to answer my questions in a friendly manner.
10/10 will stay again!
