There are many hostels in the Taksim area. But here, believe me, you will really feel like in your second home. In a welcoming environment, you will have the opportunity to chat with your roommates from different countries, and who knows, there will be an opportunity for new connections.
Breakfast is included in the room rate (please confirm this upon arrival), and there is also a vegetarian alternative. The receptionists are very friendly. 🍁🍂🌼
Especially if you are going to stay for more than a few days, this can be a convenient hostel for you. I was a guest for about two weeks and I really enjoyed it. I definitely recommend it. 👍
