The place is great and almost perfect.
Location:
Idealtepe is a little outside the center of Istanbul, it's a quiet neighborhood with a lot of apartment buildings, stores and restaurants nearby.
Transports:
The bus services are very tricky when you don't know them and when you don't have the Istanbulkart (about 13try+"tickets"money). Get one as soon as you can, it will make your trip way easier. Be sure to have plenty of 20s in your wallet because some devices don't give the money back. You might not be able to get it at the airport, it should be easier to get in a station when you get closer to the center. The "Marmaray" (the name of the south coast train to Istanbul) has a station near the apartment. It's very close and very convenient to reach the center of Istanbul.
View:
the place is awsome, it's a loft on the 4th floor of the building (with elevator) with a huge terrace. It is southwest oriented, which means that you'll have amazing sunsets over the sea almost everyday. the apartment tops the other buildings and leaves you with an open view on the Prince Islands. It is magical.
Apartment:
Nothing much to complain about, the place is a medium apartment (for 2 people) with a huge living room. Wood everywhere, looking and feeling cosy, warm and quiet. The place has everything you'll need for your stay: fully equiped kitchen and bathroom (the shower which often is a problem is great in this apartment, it even has a showerhead), a cosy bedroom with a comfortable bed and plenty of storages (maybe just a little lack of electric sockets, but nothing big). We didn't miss anything at all, it has all the comfort you might need. And if it hasn't, just ask Can 😁 We almost felt at home right away.
Landlord:
Can warmly welcomed us and was always ready to help if we needed something. He was always quick to answer and always nice with us. I'm very thankful for the way he treated us.
It is a very nice place for your trip, to stay home, to visit Istanbul or the islands, an nice place for anything you want on your vacations.
