Our 3-day stay here was great!
The Host helped us a lot with good communication, especially when we needed to do a covid test for reentry in our home countries.
She also arranged a great early check-in and early check-out, which was very helpful and relieved us from a lot of stress :)
The neighbourhood has a lovely atmosphere and great comfort in transportation and food availability, nearby Taksim square has all the places you may want to visit along your travels in the historical part of Istanbul, particulary the famous bookshops (which i strongly encourage you to visit).
Concerning the navigation there is also a lovely booklet in the apartment with the most interesting and hip places listed.
The temperature was very comfortable, we stayed in the beggining of October and though I can't account for heat in the middle of the summer, I am rather confident it should be ok - the windows don't seem to be on the sun side.
The internet quality, which was important due to a pending zoom job interview was also great!
I would totally recommend the apartment and strongly wish to visit Istnabul again and would prefer to do so starting it from staying in this apartment :)
