We stayed at this perfect apartment for 3 months. It looks exactly like in photos, very cozy and stylish. It has everything you need, even a printer. We were working remotely for all the time, it was really comfortable: the apartment has two separate work spaces and fast internet connection.
The terrace is really cool and well equiped with all furniture, when it's warm outside you can work, eat and spend evenings with friends there.
The neighboorhood is great, really modern, with good-quality restaurants and coffeshops. Just 7 minutes walking to Osmanbey metro station, from where you can go to any Istanbul point.
A few moments, just to let you know (but it didn't bother us at all): there is no elevator, so be prepared for going up to 5th floor. It's a bit cold in the apartment even with a central heating (it turns off at night) and light bulbs are not really bright.
All in all, it is great apartment for a long-term stay, highly recommend it! Asu is a wonderful host!
