I stayed with my wife and 3 of my children, "all adults" for 4 nights from the 25th October until the 29th October 2014 in this apartment. It is a spacious 2 bed apartment with the further option of a double couch bed in one of the two living rooms. The Apartment was clean , tidy and very well presented. Its in a great position , beside Sishane Metro Station in Beyoglu. (Near Taksim Square) This makes the rest of the city very accessible.
The owners were extremely helpful , starting with them organizing transfers to and from the airport for us on our arrival and later for our departure. After we arrived in the apartment and had done the necessary paperwork , Izel (1 of the owners) took the time and effort to walk us around the local area , showing us the nearby shops etc and recommending some local restaurants that turned out to be very nice and reasonable. He also took us to the local station and showed us how to buy and use the travel cards for the trams and the vernacular transport down the hill to the river.I really thought this was a nice touch.
I would have no problem recommending this apartment to any future prospective traveller to Istanbul, and I suspect I will be back in the not to distant future.
