Me and my girlfriend went to Istanbul and had no stay until the day of arrival. Luckily, I contacted Deniz who amazingly quickly reacted to my request.
Deniz is a wonderful host, she is really flexibel and an outgoing person on top of that. Her apartment is perfectly located, in Moda, a fantastic urban-chic neighbourhood. Within 5-10 min. walking distance you can access all public transport systems. The apartment was perfect for couples, we got a nice french-size bed and the room had enough space to rest down between sight-seeing tours or before a night out.
During nights it's really silent, even people with massive sleep problems will find dreamworld here ;)
Needless to say that the whole apartment looks like shown on the pictures and the apartment-description by Deniz is even understimation because you have indeed EVERYTHING you need for staying a couple of days in the amazing Turkish city of Istanbul.
I can and will recommend Deniz' apartment to all of my friends travelling there and I hope a lot of you guys will get the chance to meet her and her boyfriend (and her cat)!
