It's a great apartment to stay. There is all you need - a gas cooker, dishes to cook food, fridge, sink, shower, toilet, Wi-Fi and TV. The design is authentic, everything is clean and nice. If the host doesn't respond via AirBnB, you can call him via WhatsApp. You can find many cafes, restaurants and shops, currency exchange with reasonable prices in the neighborhood. If you want to save money, you can take HavaBus shuttle from the airport to the Taxim square and get here to YaniKapi metro station. Keep in mind that it takes about 20 walking to get to the apartment from that station. There is also Beyazit tramway station in 10 minutes walk from the apartment. Be prepared to wake up from morning Muslim pray at about 6:30 AM that plays from the loudspeakers outside. There is also traffic on the street, so it can be a bit noisy but you will get used to it in a couple days.
