We were hosted by Elnaz's mom, who was responsive and gave clear directions to get to the flat. She was very kind and hospitable, offering us coffee and cookies when we came early to drop off our luggage. She spent time to talk to us and we enjoyed conversing with her. The location is close to a subway station (4min walk), as well as a grocery store and restaurants within walking distance.
One that we would suggest is to be mindful that the flat is shared with the host, so it can feel restrictive or awkward if there isn't clear communication upfront about what is and isn't ok in the space (wearing shoes inside, use of radiator for heating, etc).
The key for the bedroom was also not provided so we would suggest asking for it if that is important to you.
