I would absolutely stay in this penthouse again. The host was very responsive and available to answer questions. The accommodations are modest and included everything I needed. A big balcony with a view of Istanbul's symbolic bridge was such a welcoming image to have a view of. Within easy walking distance to everything.
The apartment is comfortable, clean, and calm. The neighbors are respectful Turkish families. There are amazing stores, cafes, antique shops, and more where I stocked up on locally made crafts. I especially enjoyed boutique breakfast places where Buse suggested. They are only 5min away from the flat.
