The location and upstairs shared areas were nice (kitchen/lounge room). Just be aware that there is a steep hill down to the property from the main road in Sultanahmet so a bit difficult with luggage. However once settled, it is within close proximity of the important land marks.
The main issue was the downstairs bathroom, the shower was in an awkward position under the staircase with a bath. This meant it was a bit awkward to get in and out, maybe just keep this in mind for older guests or children.
There was also no self check in, but the host made sure they were there in a timely fashion to let us in.
