We have been fortunate to be able to travel around Europe for the last 10 years, using sites such as Airbnb and Homeaway. Without a doubt, this was our worst experience. Mold/mildew issues in the only bathroom, putting sheets on a mattress, only to find bugs under it. A bed that was too small for our smallest child. Waking up in the morning to the sound of jack-hammering outside the window. A view out the front windows of construction scaffolding, covered with plastic. It's terrible when you look forward to leaving such a beautiful city as Copenhagen, strictly due to your housing.
