We were a group of 5 adults and 1 baby. The apartment was much bigger then we expected. The lounge/dining area was very spacious and perfect for keeping a baby entertained. The two bedrooms (1 double and 1 twin) were also very clean and spacious. Having two bathrooms (1 ensuite and 1 main) was also very useful and practical. The kitchen was equipped with everything we needed including a washing machine.
Maide was a great host. She was very quick to respond to any queries and questions I had both before and during our trip. She even went out of her way and sourced a crib for us.
This apartment is great if you want to be near Fatih Masjid. It's a 10min walk to the main road where you can catch a bus which is very cheap and regular. It took us about 15/20minutes to get to the more tourist-y sights of Blue Mosque, Topkapi etc.
Would definitely recommend and visit again.
