I stayed here for a week in October 2022. Ece was super helpful and gave wonderful check in support. The flat was easy to find and a good size for 2 people. The building has narrow steps so a bit tricky to get up with luggage. I'm sure if you asked for help taking luggage up in advance this would be provided. Ece was super quick to respond to my messages and I received fresh towels when I asked for it asap. He was also very kind in helping to arrange a taxi to take me to the airport.
The flat is located in Beyoğlu and close to Sishane metro station. It was sometimes a bit noisy at night as Beyoğlu is a vibrant area (imagine Soho in London). I recommend Şirin Fırın | Bakery 2 (address: Şahkulu, İlk Belediye Cd. No:19/A, 34420 Beyoğlu/İstanbul) and Aheste restaurant close by. Thank you again Ece!
