Great location!
This apartment is located on a local street some few minutes away from Istiklal street (the main tourist area in Beyoglu) so it has the best of both worlds. The place is spacious. It has washer and dryer and a dishwasher which make the longer stays more convenient. As a family of four, we stayed here for 9 nights in August. The air conditioners work well. The WiFi does not work in the bedrooms so everyone needed to come to the living area to connect. The hot water was disconnected twice during our stay (we had to wait for it to get fixed) and we ended up killing a roach in the second bathroom. One bedroom is very small to the point that the small bed is pretty much what they could fit in. I think 4-5 would be the maximum number who can stay here comfortably. Interestingly, we paid the same amount although the price is set for 8 guests.
We did not cook but I am not sure if the kitchen is well equipped to do so. We used a grill pan over the stove for toasting bread. We could not figure out the Netflix and some other TV options but probably that’s just us.
We loved the local cafe, Firuz, just down the street and of course the convenience of shopping (food, laundry detergent , etc,) right on the same block. My favorite Istanbul activity, wondering around the small alleys in Beyoglu is easily done in this area.
Overall, we enjoyed our stay in the apartment.
