The stay was very good. The apartment is very well located, 2.5KM from taksim square, and the road is very easy to walk.. The area has everything you would need for long or short term stays.
Communication was very easy and smooth with Feras who really made our stay easy.
The apartment offers cleaning services with renewal of towels, etc. Which is very good and needed if you are staying for more than a week or so.
Finally, the only little problem was with the internet connection as it wasn't very stable. So if you are planning to work from the apartment, the internet might not be very reliable.
Thank you again to Feras, and to Metin.
