Apartment full of character in an area right next to the Galata Tower. As others have mentioned the apartment is 4 floors up with no lift, so not one for those with mobility issues, but a great space for those who aren't. The apartment is spacious - two good size double bedrooms - with a very well appointed bathroom (great shower! and even a bath) off one of them. Comfortable lounge area and kitchen seemed decent, not that we used it much. Also has washing machine/tumbledryer. A bit stuffy in the heat (no aircon) but lots of big windows on both sides of the apartment to open to generate some air.
Lots of restaurants in the area for meals including breakfast. We walked to the attractions we visited (Blue Mosque, Aya Sofia, Basilica Cistern, Grand Bazaar) and it took around 30-40 minutes; or at least it would have done if we hadn't stopped off on the way to take in the sights and sounds! Particularly the buzzing area along the river on the other side of the Galata Bridge (5-10 mins from apartment) - had not seen that before in previous trips and it was huge fun, lots of buzz and interesting street food.
So definitely recommended by our family!
