We felt very good, Hamed is very kind, helpful and hospitable. He offered us a bottle of water on arrival, guarded our luggage at departure, gave us a postcard of Amsterdam.
Access to the apartment is through very narrow steep stairs, which can be a problem for larger people. The weather was cool, but the room was warm and we could also cook tea in a kettle.
Otherwise, the great location and authentic environment of old town houses, I recommend to experience it!
