Istanbul is a very beautiful city, but it is beautifully smooth on how much it is huge. The city has two airports - in the European part of the airport atatur, and in the Asian part of the airport of Sabiha Gecchen. The first incomparably much more and its location is more convenient, it's more convenient to get from Ataturka to get to any place (if you certainly do not need to be in the Asian part). Every and a half minutes at the airport ataturk takes off or landing plane. You can imagine how many people and which number of aircraft. Probably there are no airlines that have no flights to Istanbul, but I would still advise you to give preference to Turkish airlines, their prices are quite loyal compared to such giants of air transportation as Lufthansa and Eir Arabia. Turkish airlines fly from very many cities around the world and very often they pass shares when 100 euros can be bought from a ticket to both ends.
Sabiha Airport is not much less, respectively, and there are not so much people there and the airlines cooperate with him simpler, because it is worth getting to the alert, then on city transport it will be Oh, how not just, And on taxi prices pieces). So, if you still decided to save (or you initially need to get to the Asian part) and fly to Sabiha Airport, you can use Pegasus Airlines, for example, a two-round ticket from Bologna (Italy) to Istanbul will cost only 130 Euro (promotional promotion), and on a regular basis, Pegasus aircraft fly from Istanbul to Kharkov and Lviv, the price of one in both ends of about 100 euros.
If you still decided to fly to the Aeropert of Ataturk and the transfer of your hotel does not provide, then you can use urban transport. So, for example, if you need to get to the area of Sultanahmet or Eminon, then directly from the airport there is an entrance to the subway, the passage costs 2 lira. On the subway you will stay to Zeytinburnu stops and transplanted to the tram, you will reach the Sultanahmet district on it.
The tram in Istanbul is slow enough and always full of people, but if you are lucky to sit down, then you will be comfortable enough. Drive as in the subway cost 2 lira. To pay, local residents enjoy the cards that are minimized, such a card itself costs 7 lire and gives some attractions (if you use the Monster of Istanbul transport - the metrbus), but for several days it is not needed for several days, therefore special terminals have been installed at each stop where you can buy tokens.
If you want to see not only historical sights, but also visit a couple of shopping centers, for example, forum Istanbul or Marmara Park, then you should use the metrbus. This is a metro from buses. He goes on the road, two lanes are highlighted for him, for which ordinary cars can not get, so there are no traffic jams. And so, if you stayed in the Sultanammete, but are going for example in Marmara Park, then you stand at Rammaj to stop Gevizlibaa (Cevizlibag), and there to transfer to the metrbus towards Beijkduz.
Metsobus is a very fast and fairly comfortable type of transport, but not at the rush hour :)
If you decide to visit the Istanbul forum (one of the largest shopping centers of Istanbul), then on the tram that goes towards Zyutinbourburn to stop Yusufpasa, there are a couple of minutes to the metro station Aksaray (Aksaray) (the same branch that goes To the airport) and come to the Kocatepe stop (Kocatepe), from the station there is a transition that leads directly to the shopping center!
