The place is amazing.
This is place has 1 hour riding distance from the center of Istanbul like Taksim and Grand bazaar but listen to my advice and never go to Taksim and Istiklal street or grand bazaar to buy stuff because there are a lot of shopping center near to this apartment and the prices are way lower than the center of Istanbul.
If you want to exchange the money then do it in Perla vista mall near to this apartment. The price of exchange would be better than the grand bazaar exchanges.
So don’t do my mistake and if you wanna buy anything buy it here not in Taksim or ground bazaar.
Also there are a lot of public transport which works 24/7
My advice to you if you wanna use the public transport is : buy Istanbul kart in the first day and charge it for 50 or 100 lira
But the better option would be renting a car if you plan to visit all historical place. It would be cheaper and more convenient.
Some advice:
City center to buy souvenir: Marmara
Don’t buy from:
Grand bazaar
Veniza outlet center
And stores in Istiklal street.
Enjoy Istanbul and enjoy the place.
