Very comfy apartment in a great complex. Besides the flat, you have free access to the pool, gym and sauna.
We have problems with ordering taxi on Uber and BITAXI (I guess it is a common problem in Stambul).
30-40 min to the Galata tower by foot. The way is uphill, so be prepared :)
If you go from the IST airport by bus, best stop is Havaist Piyalepasa not Taxim (only 8 min from that stop to the apartment).
