I stayed here for five days during Easter with family, I really can't fault it, the location was great, a 10 - 15 minute walk to Istikal street. The kitchenette and open plan living area made the holiday that much better and convenient, as we could have breakfast and make lunch for my little one, before heading out to explore every day.
If I return to Istanbul I would stay here again. Absolutely recommend!
If you want to be next door to a tram station then maybe this is not for you, however if you enjoy walking and exploring, it's a great option!
