This apartment is a lovely place to stay and Mehmet is a wonder host. He is incredibly helpful, always responsive and happy to offer recommendations based on your needs. The apartment is as described and shown on the pictures. It is clean, the kitchen is well equipped and the wi-fi is great. I booked a long stay and was working remotely so it was important to have a good connection and I had no issues. It is centrally located but the neighborhood is still quiet, calm and very safe.
The location is superb, you will be a few minutes from Istiklal where you can find shops, restaurants and a metro stop. You are also a few minutes from the Galata tower. Then there is Karakoy also a few minutes walk where you can find more restaurants, great coffee and the tram that easily gets you to many touristic sites across the Galata bridge.
I highly recommend this place as well as the host!
