My wife and I spent four nights in Irem's lovely apartment on what was our first time in Istanbul. The location is perfect - just by the Pera Palace hotel and Soho House, with all of Beyoglu on your doorstep, but just over the highway, so it's quiet at night. This was definitely our favourite part of the city, but we love walking and so strolled from here all over - up to Taksim and as far north as Sisli, south to Galata and across the bridge to Sultanahmet and then on to the Grand Bazaar. We took taxis further afield to Balat and the ferry to Kadikoy Moda. It was a perfect base.
There are two beds, and we chose to sleep upstairs, where you wake up to a wonderful view of the old city. The flat was very clean and modern, the bed was comfortable, and we were grateful for the AC, as it was an unseasonably hot October while we were there. The terrace is massive.
We had a fantastic holiday and want to come back - we would love to stay at Irem's place again, and can highly recommend it.
