I really liked staying at Dalma's apartment. I've spent there 5 days but I would stay even for a month with a great pleasure. It's very cosy modern apartment with a lot of plants, great library and lots of lovely little things here and there. Spacious living room, comfortable bed, washing machine and fully-equipped kitchen. You'll get everything you need for a comfortable stay. Apartment is perfectly located in the middle of Kadikoy district. Kadikoy pier is 10 minute by feet and Metrobus is at 7 minute walking distance. Damla is a great host. Very attentive and caring. So I can strongly recommend staying at Damla apartment if you travel to Isanbul.
