The taxi rank is at the end of the main street (near the dolphin roundabout)
You'll see the yellow taxi's.
Where abouts are you staying?
If theres a shop near your apartment, if you go in and ask for a taxi they will normally call one for you
The other thing i will say is I find taxi's quite expensive for members who know calis.. i live near the seckin market and frm the taxt rank to the home he charged me 7ytl!!!!
Jump on the Dolmus.. its 1.50 and you can get on and off where you like... when you want to get off just tell them 'stop' and they'll stop for you : )
Im a big fan of the Dolmus... beats walking anyday!
