Make sure you understand how many bedrooms the apartments have. Some beds are in common areas and you need to walk through the actual bedrooms.
We specified that this was a business trip and that we would need a separate bedroom for each person. Some of the apartments that the owner claimed to have two rooms were, in fact, one-bedroom apartments. When we addressed the issue to Marcella, she said that this is how Airbnb works and refused to do anything about it.
We had to rent an additional BnB to accommodate everyone.
