You can’t beat this location! Right next to Galata tower and the street has amazing options for food, coffee and dessert.
Check-in was seamless, the cohost helped with it inperson, it would have been a hassle to find the place after hours if you are on your own. Beware if you have large suitcases, its some work to get to the apt floor with the winding staircases.
Tip: If you want to save some money book your own taxi to and fro for airport as it was way cheaper than the option host provided.
