Hüner was very helpful once we arrived to his apartment. it is located just in front of the galata tower, a beautiful placed but also very noisy. Especially the 2 rooms at the front of the building. Consider use earplugs.
The apartment is not small, enough big for 7 persons. We felt confortable.
I would recommend a couple of things that can make your stay much more confortable:
1 Use blackout curtains: as the apartment is really close to a very popular monument, it will be always illuminated outside. All the light will get into the room, becoming uncomfortable
2 consider change some of the mattresses. some of them are very old and with "U" form
3 we had some issues with the arrival. I did not have a Turkish number or internet, so I had to get some help from a waitress. he called Hüner and finally could get to the
department after waiting some minutes.
Thank you for your kindness Hümer, and always being open to help us with our needs.
