This apartment was great for myself and three friends (one bed each). You are right in the heart of the Beyoglu district of Istanbul, from which you can easily access the main sites of the city by walking or on the efficient public transport.
Note that the apartment is on the small side but this is to be expected considering the location. There is so much to see in Istanbul that this will hardly be a problem.
The rooftop view is one of the most special sights I have ever seen. I would highly recommend this place and the communication was very helpful considering we didn’t speak a word of Turkish.
Thanks!
