I have rented flats in Europe many times and been very pleased. Except for my recent experience with Barcelona Flats, a rental company based in the UK. The flat was dirty and smelled musty. The bath towels and linens were so threadbare and mildewed, they would be impossible to use. I told their Barcelona rep right away that we could not stay in the flat but they refused to return our deposit or apologize for the state of the flat.
