I cannot fault this place, our stay was amazing.
we booked this apartment for 4 adult males, although this was a 3 bed apartment, the host sorted us out an extra bed for a additional fee.
from the outset communication was fantastic from Buse, she provided us with a video over whatsapp how to access the apartment and the security codes were provided over email a couple days before we arrived so there were no issues.
the apartment was very spacious and clean, the location is amazing, its away on the Asian side where more of the locals live, with a great view. you have the waterfront less than a min walk away, the public ferries which are probably the best public transport I've been on are just a short 2-3 min walk away and costs 8 lira(about 40p) per journey to use and goes towards the main areas in Istanbul. I genuinely have fallen in love with Istanbul and would not hesitate to come back to the same apartment.
There are some great restaurants around, got to give a shout out to Kabitim which is like 1 min walk away we were there every night, great food and vibes.
also if you're Muslim, there are many mosques just a stones throw away, one is literally behind the apartment.
i would not hesitate to recommend this place to all my friends and family.
