We stayed in this apartment for a week in Oct 2021. It had plenty of space so that the 4 of us were never in each other's way. Having 2 bathrooms helped, too. Had all the amenities, including heating and A/C which luckily we never really needed.
The location is accessible by foot, and there is a lot to see and experience within walking distance. It is a bit of a climb from the sea level, so with heavy luggage it would be advisable to use the Tünel funicular to get to the top, and then to go down a little bit instead. There is very little traffic on the street, so it is generally quiet (aside from occasional prayers from a nearby mosque).
Izel was a really nice and helpful host, waited for us on arrival, provided all the necessary information, and helped us arrange a taxi when we were leaving.
