The apartment is on great location and almost close to everything. It is literally about 5 minute walk to Galata Tower, also close to a lot of cafes and restaurants which are open as late as 1/2am!
The host was accommodating and great with communication. He even reserved PCR test for us and the nurse came to the apartment.
The Airbnb is spacious for 3 people since it has 3 beds. It was equipped with almost everything you need. The balcony is small but has a great view of Ayasofia. I would recommend it and consider staying here again in my future endeavors.
