Sejo was a super communicative and accommodating host! Apartment was actually more spacious than the pictures showed. Location was pretty good - not perfect as its a few blocks off the main path - but great value for the price. Also, has an elevator which is worth noting since most of the units in Istanbul don't.
Only one big issue we had was the wifi service was quite slow and dropped frequently in the apartment. This normally wouldnt be a huge issue - but we were traveling for work and so had frequent voice and video calls for hours a day. This presented a problem and we had to go buy seperate internet hotspots to be able to work.
Giving Sejo's place 4 stars overall. Thanks again!
