The communication with and support of the owner was very good. We could check in already at 1 pm that was very helpful for us. The apartment is located really close to the Galata tower which means you can reach many things (esp. restaurants and bars) in walking distance.
The first look of the apartment was good, although it was really steamy and warm in the apartment. Unfortunately I was a disappointed from the bathroom, which does not make the impression as the photo might suggest. Some things are broken (e.g. the glass shelf underneath the mirror, which just not exists anymore), some things just look not nice anymore (e.g. toilet paper holding) and some things are just not ok (e.g. mold in the shower and a hole in the floor which is "closed" with a tissue or something).
The living room area and kitchen area seems nice and the size of the bedroom is also fine. The mattress however could be improved and the bed sheets should be really clean (we found a little dirt on one of the cushion covers).
I have given this feedback also to the owners and he promised improvements. Let's see.
