The location is great, close to the lively Istiklal street. Every Sunday there is farmers market right across the street, with lots of cheap and fresh produce. There is a decent grocery store nearby. Apartment heater is great: very powerful and easy to use.
The building is on a hillside, so to enter the apartment you need to climb one flight of stairs to reach the second floor, but the windows on the other side are at the ground level. We kept the shutters closed all the time. Sound insulation is very poor: you hear a lot of noise from 7 am in the morning until almost 1 am at night from neighbors talking, locals arguing on the street, vendors unloading small trucks for the home improvement store nearby. The unloading of cooking gas tanks is especially loud. The kitchen and bathroom sinks need unclogging: they drain veeeery slowly. The shower drain is fine. The kitchen stove it tiny: it can only heat one pot at a time. The washer works fine, but there is almost no place to hang dry the clothes. The wi-fi internet is fine, albeit a little slow.
The main negative issue is the uncovered brick walls (and parts of ceiling). Whenever somebody closes the metal building door, the dust/sand falls from the bricks. A lot of it! We had to move the bed away from the wall in order not to wake up covered in dust/sand. Kitchen table also had to be moved to avoid dust/sand falling in our food. Something has to be done to structurally reinforce the bricks in order to prevent them disintegrating slowly.
