First of all, I'd like to thank the host, as he managed to make the check-in, stay and the check-out as comfortable as possible. I was receiving guidelines about almost all issues that could arise in relation to my stay. Very well done!
When it comes to the apartment itself, it is a nice alternative for those, who need an adequate alternative to fancy insta-locations. It was a little worn-off, but clean room with two single-beds stacked to each other to make a double-bed, a small coffee table, a couch that has been living a long life, desk and a cabinet. There is a window, but it opens to a well-yard. The bathroom and the kitchen are fine, no fancy stuff, but does the work. There are a functional fridge, a washing machine and a stove. The neighborhood is silent, and safe, there are several shops and cafes around in a distance of 2-3 mins walk. For that price, it's a good option to stay several days in a very central area in Istanbul.
