Excellent location a stones throw away from the Galata tower. It was a fantastic base for us during our week in Istanbul a short walk away from both the metro and the tram. We ended up walking most places. The supermarket is just around the corner where you can pick up groceries.
A couple of things to note: the apartment is very close to a mosque so the call to prayer can be quite loud in the mornings. There are also many cats living in the building who sometimes try and sneak into your flat. If you leave some food for them outside they’ll be happy!
