This place is simply AMAZING. Beautiful and well designed. It looks like the photos but I think bigger when you actually get there. Its right near the Galata Tower that actually you can see it outside your window. A perfect central location for a cab or uber to find. Or even for you to find while walking. Right outside your door there are shops and a little grocery store. The neighborhood is adorable and safe. Considering as a girl I was walking home alone sometimes, I was perfectly fine.
The apt was equipped with everything you need, including hair dryer. Plenty of sheets, towels, which I've experienced in the past at other places is sometimes is lacking. Also plenty of closet space to store your clothes. Kadir even had maps and guidebooks.
Kadir and his staff were utterly professional and very communicative with efficiency. When we needed an extra set of keys, we were given one the next day easily. Also Alexandra who works with them greeted us exactly when we arrived and provided us with a tour to show us the place and how everything worked.
If I were to go back to Istanbul this would probably be my top choice just cause of location. Yes it is a 4th floor walk up but its not really a big deal and for the great apt you are getting, its minuscule of a price to pay. Def recommend for anyone considering staying in Istanbul.
