Jonas, thanks for your feedback. This is a budget home stay, making it affordable to everyone, very unfortunate that we are not able to match the service provided by 5 stars hotel or Airbnb that charged 5 stars pricing. Unfortunately, it is not dust or hair on the floor as claimed. Marble white floors are common in Asian houses, the scratches and crack lines on a marble white floors, were due to luggage and dropping of hard objects in the past, it would look similar like hair and dust with lines. We are very strict on cleanliness, during your stay, I didn't receive any report in regards to this issue? In regards to mattress, I believe you are not used to the pocket spring mattress, this mattress is also very common in Asia. However, I will look into this mattress issue and upgrade it, as this is the first feedback about mattress.
