During our stay, the building was undergoing facade restoration / renovation works and as a result there was scaffolding around the building. This prevented us from opening the only external-facing windows in the living room, which provided most of the ventilation and natural light to the apartment. In addition, there were workers undertaking often noisy works throughout the day.
We were not told of the works or the prospect of disruption before booking or arriving. We raised this as an issue with the manager of the apartment (Barbara) and sought compensation. While the amount of compensation ultimately required mediation by AirBnB, throughout the process the need for compensation was accepted by the owner and there was regular communication with Barbara.
A few other points about the apartment - the location is great and its proximity to a metro station is very convenient; we struggled with obtaining a good wifi signal outside of the living room; the TV is very old; Barbara is very responsive and helpful with minor issues or requests (for example, she brought us detergent and sponges for the kitchen when we saw there was only a very small amount left)
