Everything is accurate as described. The only factor which could also be added is the house being on a hill, which could be a bit of hike for someone not used to it.
Check-in:
From Istanbul airport, I took HAVIST-16 direct bus to Takseem Square. The ticket cost was 67TL or $5CAD. Afterwards, it took me a 45 minutes walk/ferry to reach the room from Takseem Square.
Alternatively, I could have taken bus#55T from Takseem Square, which would have dropped at Fener station which is a five minute walk from the house. On my way back to airport, I too this bus and it was a 17 minute ride to Takseem Square, and then took HAVIST-16 to reach Istanbul Airport. This route was recommended by the host as being the most direct.
The neighborhood has good restaurants, which are cheaper than those at Sultanahmet.
Overall, a good place for a short stay for those who are on a budget.
I would recommend.
