I contacted the houseloft agency on our arrival after the flat detected dirty and not prepared for visitors.
The agency's customer service on Friday offered to send someone immediately to clean the bathrooms as they seemed recently used (disgusting) and the small bathroom's floor was covered by red dust after we opened the window. The wardrobes and floor were dusty and a ball of hair found behind bedroom's door. The towels that were provided weren't fresh and the couch on the living room wasn't suitable for an adult to sleep as every time you were trying to turn the whole couch would lean on one side.
The door in one of the bedrooms didn't close properly.
Second pair of key didn't work for the entrance door downstairs and when I asked the agency for a new one they took the keys away but never replaced it and left our group with one pair of keys.
The above incidents left our group with mixed feelings and I feel embarrassed as I was responsible for the booking.
