Hi Eva, I can assure you the unit had been cleaned thoroughly, there were some marks that are simply left in a place that naturally happens in time, but is no indication of an unclean place. However, I undrestand where you are coming from so for your peace of mind we offered an additional cleaning right away which you declined and your husband demanded a full refund in a very disrespectful way. I’m just guessing you had just changed your mind about your stay at the unit. The interaction was so rude and angry that the best option for us was to issue a full refund. However I do take this very seriously and going to take on some maintenance items to change the perception of cleanliness for those spots and I only hope my other reviews would speak for my hosting style.
