I am super happy me and my boyfriend decided to stay in this apartment. The people working there were so friendly and always willing to help from early in the morning till quite late (we arrived at 23.30 due to a delay of our flight, and that was no problem). We were so happy with the location everything was so close (E.g. the Galata tower was only 5 min walking distance). The roof top was amazing with an amazing view on the Bosphorus and a super amazing spot to enjoy the sun while drinking a coffee in the morning. If you wanted your room to be cleaned it was immediately (small and cozy room).
The only thing i would not recommend would be the breakfast. The rest was amazing and we would be happy to come back one day.
