Probably the perfect storm. The unit we stayed in was larger than expected, clean and very well equipped. However, the chemicals used to clean the unit as well as outer halls and elevator were strong. The first night of our stay we were able to open windows and have fans circulating air, but the next morning painting started on exterior of our unit and all windows were covered with plastic. The management company said we should've received a text regarding the painting a couple days prior to our arrival, however, the only message, was on the Friday before our departure. Fortunately, the window coverings were only on for one day, however, painters were onsite and on our decks during most of our stay. The management company staff was friendly and empathic, however, could not accommodate our request to move to another unit. Before calling the management company, the day after we arrived, I did check online to see if they had other availability, which it appeared that they did. In addition to the painters being onsite, we underestimated the noise from the nearby construction.
