We stayed for a week and thoroughly appreciated the place! It's spacious, comfortable, and feels like a home. We worked entirely online and had no problems with the internet. Zoom calls performed flawlessly. It's right near to the bus shuttle station, so getting there from the airport was a breeze. Just take a HAVABUS from the SAW Airport for about 27 Liras (I think), and it will literally stop at the last station which is literally opposite this apartment. This was the best thing about the place. You literally don't need a taxi from the airport at all.
You'd also be quite close to Taksim Square (like 5 minutes walk), which is a great place to roam around and enjoy the incredible amount food and stores on İstiklal Street. Because of its convenient location, the street can be noisy at times, but we didn't mind as it wasn't too much to cause a major sleeping issue. The shower had hot water the entire time we were in it.
Only issue was that there was no microwave in the house, but a small oven - which meant that we had to heat everything in the oven and didn't have a quicker method of heating things in a microwave. Bit of an inconvenience for sure.
Timur is a wonderful and friendly host! He was always in touch and responded swiftly to questions.
