We had a horrible experience here. The worst accommodation ever! The apartment is located in a semi-basement, therefore there were no windows and there was much dampness and mold. The smell and humidity made breathing very difficult. This is no place to stay, not even for free! The host knew I travel with kids, at least for their sake he could inform me about the conditions in the apartment. We avoided staying in the apartment during the day and went there only for sleep. Even so, I couldn't sleep in these conditions.
I knew , from the apartment description, about humidity in the air. But the description should also say about dampness and mold, just to be accurate. DO NOT RECOMMEND AT ALL!
