Apartment is exactly how it is on pictures, it has everything needed, location is perfect, few steps to Galata tower and Istiklal street. Check in and check out are very smooth, overall communication was great! Apartment is very cozy and stylish, very spacious.
The only minus is the noise at night. We stayed during hot days in Istanbul. Apartment has no air conditioning, only fans in the rooms. The fan is a bit noisy, it disturbs the sleep. With windows open you have noise from the street (cars from the street, noise from the cafes; people stomping on the wooded stairs of the building where the apartment is located). But without the fan and with windows shut it is too hot in the room.
During usual days (without heat) I would definitely recommend this stay.
