I have stayed with Fatma and Hasan several times and it is always a lovely experience. They are wonderful hosts, very accommodating, and ready to help with anything you need. It is an excellent location for getting to many popular spots in the area. It is easy to spend all day walking around exploring the neighborhoods of Beyoglu, Cihangir, Galata, Karakoy, and more. The ferry station at Karakoy is also easy to get to either by walking or public transit and this will take you to some great spots to see on the Asian side of Istanbul. Eminonu where you can find the Grand Bazaar and the Spice Bazaar is also very easy to get to from here. Thank you Fatma and Hasan!
