I was living in this apartment more that 1 month. Place is really clean, nice and stylish, fast wi-fi, comfortable bed, there is everything for a comfortable stay. Located in a safe quiet area, not far from the main attractions and transportation (but you need to climb up a bit to get to Istiklal or some nice cafes).
Lacot is a very caring and pleasant host, he was always online, ready to solve any issues or help with my questions.
I would definitely recommend this place for a long stay.
