We had the pleasure to spend three days at Neriman's apartment while visiting Istanbul. First of all Neriman is probably the most friendly, considerate and helpful host you can get. Our flight landed late and she was there at 1am waiting for us to check us in and make sure we felt right away at home. She gave us a ton of recommendations and was always there to make sure we had everything we needed. Her apartment is located at the third floor of a historic building right next to the Galata Tower. The area has a ton of things to do and it is a walk to everything, from Karakoy, to Aya Sophia, to the Blue Mosque and Taxim Square.
Highly recommended and we hope to be back again and have more time to hang out with Neriman.
