I would not recommend to stay in this apartment until the host does not completely remove the mold from the walls.
Plus:
Warm and kind welcome, even late in the night.
Close to all sights by foot.
The host ordered an airport taxi for us.
Minus:
A lot of mold on the walls (room and bathroom), therefore very bad, moldy smell and very unconfortable to stay in the flat.
The apartment was not cleaned properly.
Too slow or no response to messages, no proper solution of our complaint about the condition of the flat.
