This is a lovely place for a home away from home. I stayed for 2 weeks, had some minor problems (this is not a hotel so it's fine) but overall a great place to stay in Istanbul. The area is hip and trendy, you can walk everywhere, lots of great places around. Apartment itself is cozy, spacious and very nice, bed is comfortable. It can be noisy since windows face the street but mostly it was fine.
Would love to stay here again if visiting Istanbul again in the future.
