The house was located nearby taksim, with bus and metro we arrived to all locations we wanted to visit within less time. The house was, especially for turkey, in good condition and very clean. There was even a beer for us in the fridge and some chocolate on the table! Only the toilet, which didn't always work like we wanted, was an enemy sometimes :D
By the way, we can recommend the small market directly outside of the house for buying. The price is not higher than in other supermarkets we visited, but it is easier for carrying things and also the staff was very friendly! We will definitely visit this supermarket again :)
