The walls of the apartment have a lot of black mould on them, especially the kitchen and the bathroom (other rooms probably also have it, but painted over). When I checked in Marta opened all windows, which I soon realised was to get rid of the smell. Mould poses a serious health risk, especially to people with respiratory conditions, so I left that evening and received a refund, but it cost me a lot of stress and money to spend my holiday in hotels rather than in a flat as planned. Please do something about it or stop renting it, it is not in a livable condition at the moment :-( Marta was very nice and communication was great so I feel bad for leaving this review but the apartment is really expensive and there is no warning about the mould anywhere.
