This was a great stay. My wife and I stayed at Laurent's apartment for 1 month. We were working during the evenings/nights and during the day we would go out and walk around Kadikoy & Moda, or travel to the european side to visit the main tourist spots.
The apartment is shown 100% accurate in the listing. The wifi is great, and it has everything that you need to be comfortable. The kitchen is well equipped.
There location is amazing. It's about 45-55 minutes from the main tourist places like the Blue Mosque, Hagia Sophia, Taksim Square, Galata Tower. You can easily travel there from the apartment using the metro (10 minute walk to the station) or by ferry (15 minute walk to station).
The area surrounding the aparment is also great. It's located in a very quiet street, ideal for resting at night. But you can walk a few blocks and find great restaurants, backeries, coffee shops, etc. It's also a great location to walk to the shore and enjoy the view of the ocean.
Definitely would stay here again!
