Good points: The flat is perfectly located and it is equppied as described.
Bad points: The flat hat not been cleaned after the last guests checked out. Charles told us that "he asked the previous guests to leave the flat clean". In fact the flat was unbelievable dirty: mouse droppings under the table, mould in the kitchen, old towels on the bathroom floor full of hairs, stains and dirt everywhere. When we told Charles he sent his brother to clean but that didn't change a lot.
The (negative) highlight: On the second day we got a message from Charles, saying that we need to talk because he was in the flat and saw that we moved furniture and he accused us of being more than two people because we used to sleeping couch. So he obviously went into the flat without telling us and he accused us falsely. We moved the table because it stood in front of the heating and it was very cold in the flat. Nothing more.
So overall this was our worst AirBnB experience so far and as long as Charles does not begin to clean the flat regularly we cannot recommend staying here.
