This is my review as a tourist who is first time in Istanbul.
Apartment has an open air balcony with amaizing view to the bosphorus. We just enjoyed it. Condition of apartment is OK.
Location of the apartment was not suitable for the family with small kids. Metro station is actually in a close distance, however there are too many stairs to climb to get to the address from the metro station. Of course, there is always an option to use a taxi from the station to the flat address. Apartment building itself is old and there is no elevator, so be ready for some heavy lifting exersices if you have many laggages from the base floor to the first floor.
We had cleanliness issues during the check in, some leftovers found from the previous guests, also bathroom wasn't at the best state, for which Cihan refunded service fee immediately.
We also used Cihan's offered from/to airport transfer services for additional charge. Cihan helped easily with our last minute route change from different airport to different destination than initially requested addresses on our arrival to Istanbul. Really appreciate for this! On the way back to the airport, old car transport arrived.
Cihan is a great hoster, he is very quick and operative for any quries.
If the question arises, wheather we come back to this apartment, it is NO :)
