We arrived later than planned due traffic but that was ok for Aylin. We felt welcome when we arrived and Aylin was very helpful. Her apartment is located in the neighbourhood we liked the most (Beyoglu/Taksim) and is also close to a metro station that takes you to the sights of Istanbul.
The apartment has everything you need for a pleasant stay and has a great shower! During the night we were woken up by a few times by the call of prayer and the Ramadan drummer but the bed was so super comfy that we quickly fall back asleep! So we didn't mind that at all. We would highly recommend staying in Aylin's apartment!
