I rent flats everytime in Taksim since 6 years and this one is now my favorite place. All commodities you want are here (washing/dishes machine, microwave, coffee machine...). The building is very modern and new with shops nearby.
Good situation (10mn from Taksim on the way to Aksaray and Ataturk Airport), many taxies nearby.
I was surprised to find good breakfast included on arrival (cake and local bread).
I strongly recommand this place definitely.
