We stayed for four nights in this fantastic apartment. It has ca. 15 - 20 m of window front and provides an overwhelming view in the morning, during the day, in the evening and by night overlooking the Marmara sea. There was a lot of space for our family of five and the sofa area as well as the dining table were excellent hangouts to enjoy the openness of the space and the great view of the city. Many apartments on this side of Taksim will have the same view but the width of the window front is adding more, much more.
The apartment itself is very quiet and we heard very little from the neighbours; a litte noise came rather from the night clubs up the hill but we are not that sensitive to that.
We came by car and it was very easy to find a guarded overnight parking garage in the neighbourhood. We paid ca. 6 € per night, which we found affordable, especially taking into account that Taksim is a hot spot for tourists and locals.
The apartment is close to Taksim and thereby, by definition, on a hilly area and you need to be prepared to walk up and down to reach public transport. We found Findirli station very convenient to get into the old part of the city by tram, we walked to Besiktas and the Dolmabahce Palace, in the other direction, Taksim and Istiklal Caddesi are minutes away from the apartment... We spend also some time cooking and found all appliances necessary, although the kitchen could be just a little bit better stuffed.
