Apartment is really close to public transport stations, making it easy to get anywhere in Istanbul in 10-30 minutes. Neighborhood is very quiet and calm, so there won't be issues with noise keeping you awake.
As far as hosts are considered, they are extremely welcoming and helpful, replying quickly to any questions and concerns we had regarding getting around.
All in all, if you're looking for a relaxing vacation, I would recommend this accomodation greatly.
Thanks for all the help, Sophanai and Anas!
