We have been in Istanbul for 4 days and stayed at Invictus residence even though we had no chance to meet Oytun in person the apartment was really nice, very clean (we had new towels every single day and replacement of shampoo, shower gel hair conditioner and soap). It had the feel of a hotel room although we've really enjoyed our stay. The room looks exactly like the pic's and it is in a very central position with taksim and istiklal in 2-3 min. walk. The metro station is 2-3 min. walk. I defenatelly would recommend this residence to everyone.
