The Orange Studio was exactly as described and Fatih, the Host, was really nice, helpful, and responded very quickly. He was uncomplicated and explained us many things about the room as well as about the city.
The studio is not only near the metro, but also only 15 minutes walk to Taksim square. There are many nice restaurants and shops near the studio.
The terrace is really huge and very beautiful. The room is small but there is everything you need. (internet, towels, kitchen stuff, and so on)

We stayed for more than 10 days and I can fully recommend this apartment to anyone
