Man what an amazing place. Incredible view, grocery store attached to the building, good restaurant inside the building, nice pool in the building gym, great kitchen, great bed and shower - everything was fantastic. Especially the hosts, who helped me when I got sick and when I broke my travel adaptor.
It's a 20 minute drive to Kadikoy, a 20 minute walk to the metro and a 10 minute walk to the bus. Easy to get everywhere, and Irina even gives you an Istanbul Card so you can use the transportation easily.
I can't wait to come back.
