We have been staying in Serdar's building for few weeks and we rented this apartment on entrance floor for a first week. It is very clean, bed is super comfy, linens and towels are fresh and smell beautifully, like at home. Apartment is not new, however it is well maintained, clean and functional. Serdar is highly responsive, making sure that any issue is resolved quickly. The apartment is in nice neighborhood, not far from Taksim. Lots of grocery stores in few metres from entrance. If you go uphill you you will have some steep walk, but manageable and Taksim metro station is nearby. If you go downhill you can catch tram from Kabatas. Overall, this location is very well connected and good choice for city break.
