Lovely spacious flat, great location, speedy communication with an added bonus of one of the friendliest shop keeper at the entrance that sells bags. We messed up our pick up by booking the wrong day and he offered to call around to try and find us another car. He was really kind and kept checking on us. Plus his bags were pretty good quality so we ended up buying some bags from him LOL
Had a few hiccups with the flat and the landlord responded and fixed it quickly.
It's in a great location quite close to the Galata tower so in the evening the outside can be a bit noisy but the back rooms are quiet.
It actually quite nice to sit in the living room after a days walking with the windows wide open. Just listening to the hustle and bustle outside and watching the lights twinkle outside and the boats floating on the Bosphrous :-)
I would stay again :-)
