You've never been in better hands or a better place than this Airbnb. The level of service and attention and speed of answers to questions and requests is better than I've ever had and I live in Airbnb's around the world 100% of the year.
The unit is sublime! Top-floor, penthouse-style with the largest patio in the city I imagine. It's located in a quiet area of town with an amazing cafe (Welldone) 1 block away and a lounge/bar/restaurant 1 block from home too (The Townhouse).
Do you run or enjoy sunset walks? The walkway path along the river extends for km's and is 2 blocks away. There are coffee spots and gym equipment on the waterfront as well. AWESOME!
The home is modern and has all the comforts you would expect from a higher-end apartment. The beds are also super comfy and you find yourself waking up refreshed and ready to take on the day.
Enjoy your stay when you arrive. This is a perfect place to base out of for your Istanbul adventure.
