We found the apartment pretty much as we thought based on the listing and prior reviews. It worked out really well for a family of four with our youngest kid around 10 yrs old.
The bathrooms are a bit small but we expected that given it's the old town. It is a typical old building that maximizes the space and, in our opinion, does a very good job at that. There might be an odd smell you may experience once in a while in the bathroom but that's probably because it's old plumbing. We are generally finicky about cleanliness and smells but this did not bother us at all.
The highlight is the terrace/balcony that we enjoyed every single evening. Of course, being close to old town and some good restaurants was also a plus. Generally, the apartment was quiet from outside sounds.
The host was super helpful and even willing to even call Turkish Airlines on our behalf to help find our luggage. The host also figured out how our luggage could be received if we were not home (we ended up being home when they delivered though).
In short, if we were to go back in time, we would absolutely rent it again.
