I think it's the best choice. Galata tower is near your window ). Very good restaurant is under your window. Great and very romantic view from your window.
We was pleasantly surprised that it is very easy to go by foot to the main sights. Just on the next the door street turn right and in 10 minutes you'll on Istiklal. Turn left and in 5 minutes you will find a tram near Galata bridge. After 3 or 4 stops you are on Sultanahmet where all main sigts are located.
Inside appartments is the same as on the photo.
Eyüp is a superhost, he provided everything in details: meet us, told about nearest places, kept in touch... and showed great view from the rooftop)
We didn't found any disadvantages and we are very happy that we found this appartment to stay.
Highly recommended for romantic weekend in Istanbul!
