Location is immaculate. Right at the heart of Karakoy/Taksim district. Easy access to the rail system and Bosphorus ferries.
Unit is ideal for a couple, ok for 3 people as advertised. It's a cute little unit. Very close to restaurants and bars, so you don't have to spend money on cabs , all you have to do is to go down and walk around. Karakoy is the rising star in Istanbul night life, so you won't be bored.
Unit has all the essentials. Hosts are very nice and they are very quick to respond to text messages, I would say almost immediately.
One thing to note is that the building doesn't have an elevator, and climbing for floors could be a bit of a challenge. I didn't mind it, and I actually considered it a good exercise.
Overall, it's a nice cozy unit. One plus was that the TV was setup for Youtube premium and Netflix account, so you can watch the shows without worrying about signing in. This place will be on my fav list if I visit Istanbul again.
