Ali is very hospital and can provide any information that you may need.
Flat is clean and spacious, bed is comfortable, wifi is great and absolutely enough to make video calls on Zoom, kitchen has all the facilities but they are not in the best condition. Windows in the bedroom facing the street and Istanbul will surprise you with a lot of noises at night or morning (school yard nearby or fighting cats under the window). Ear plugs are necessary but a bit uncomfortable. In the end of our monthly stay we have accepted all the noise and had peace in our minds after all.
