I highly recommend this place, 10 min walk from Osmanbey metro which can take you to Taksim square, it's just the next stop, super markets MM gros and Carrefour just near it, lot of shops and restaurants 3 to 10 min walk, Nişantaşı just 10 min walk. We can hear the calls to prayer 5 times per day thanks to the mosque which is just in front of it, I was happy for that so I don't have to check it on my app, but it lasts max 2 or 3 min.
The host was answering very quickly when I had a question. I really felt as if I was at home!
