I arrived late in the evening, but Christa and Zach informed me in advance how to get there and to enter the apartment. The communication always was very good, even I didn't see them much (especially Christa ;-)).
The room was like described, clean and nicely decorated. I liked the short manuell about the housesharing and tips for food, site seeing, public transport, etc. Bathroom sharing, storage of food or beverage in the fridge never posed a problem.
