A nice apartment. Though may seem quite small, but we comfortably stayed there for 2 nights as a family with 2 adults and 3 children (2 teens and 1 pre-school) thanks to good space usage. It has a big private terrace/roof with a Bosphorus view, with a BBQ stuff, though we didn't use it as it was quite cold and windy there already, in the October.
A manager that checked us in was extremely helpful and friendly. He also provided us a parking place just near the apartment.
! Be aware that the apartment is on the 4th floor by a quite narrow spiral staircase, and there's no elevator.
Overall, good value for money.
