Staying in Dilek's place was great, she has a very good taste when it comes to style. She was really helpful on a few tips that we needed. The location is great too.
The only thing I would like to mention is that the apartment is in a second floor without elevator (in case someone has a disability).
Besides that, the apartment and Dilek are both an excellent choice for anyone, if we come back to Istanbul, it's going to be to her place.
