Eyüp is very helpful, he always answered our questions and gave us good recommendations. He also helped schedule round transportation for us at a good rate.
It's important to know that the appartment is in a hill, and there are 2 sets of stairs, but I guess it can be hard to find a place in Istambul that is not like this, so if the stairs are not an inconvenience for you, this is probably the best option, with a GREAT location.
5 min walk to the tram. 1 min walk to AMAZING Lebanese breakfast spot, convenience stores and trendy shops. Really close to Galata tower and İstiklal, which are great areas to walk around and shop/eat/DRINK after you have spent the day discovering areas that are further away from the apt.
Plus: Good water pressure in shower.
We would definitely choose this place again.
