Beautiful house located in the lively neighborhood of Cihangir. Totally recommend it if you're a family/group of 3 or more travelers. There's lots of restaurants around so that's a big plus. Also, walkable to both Taksim Square on one end and the gorgeous Galataport on the other end. Just a word of caution though, the streets of Istanbul are super hilly so the walk can get difficult.
The only thing if I may nitpick is that the house only has one air conditioner located in the dining area and it may not really be all that effective in the bedrooms.
Our host Zen was very prompt in responding to all my queries and also bought a set of new utensils to make milk tea. I'll definitely consider staying here again if I'm back in Istanbul.
