We arrived late in the evening, neither Bibiana nor someone trusted from her could meet us. She told me to call her neighbors who should be aware of us, but no one answered and opened the door until we called Bibiana, so she called them and asked to enter us. They all were at home, but ignored our calls :) the flat itself is very compact, full of hosts' staff. We slept on the sofa, because it was too hot in the room with prepared bed (its like a second floor just under the roof). Cleanliness was moderate. Location is unquestionable benefit - in the heart of the city center, close to everything and full of cafes, stores, etc. as we didn't have a chance to speak with someone in personal during our stay, I felt lack of instructions/communication from host side. I believe this is related to Bibiana's own travel and not a regular thing. Overall, location is recommended to stay.
