About the noise, I did clearly tell the guests no loud noise after 11pm when they checked in, there were only 2 girls, at check in. We didn't live onsite, can't monitor 24 hours. I truly apologise, we will think some way to stop guests partying till midnight.
The mattresses are mid firm, as most of guests from US and Canada love soft bed and The continental guests prefer hard beds. When I travel to Continent( such as France, Spain etc), I tend to book American chain hotels, as the beds suit my family's need. We have guests from (Website hidden by Airbnb) left excellent reviews about our beds.
You booked one apartment with 2 rooms to sleeps, one bathroom. When you complaint at arrival, we provide you 2 apartments with 3 bedrooms, 2 bathrooms, with large roof terrace. I believe I had tried to as accommodating as possible.
I don't how dust had went to 2nd floor, where you were staying, as the work was 2 floor away from you, at lower ground floor. I apologise.
You had 2 kitchens, I believe there were more than enough cooking facility for 5 of you.
Above all, we had offered your great deal that each apartment you had paid only for £100 per night during the Christmas. You had stayed a beautiful decorated apartments with around 100 square metres in total. The total you paid won;t be enough to book in any decent hotel in the area, is only enough to pay for a room(about 12 square metres in a hostel sharing with 5/6 people with sharing bathroom etc.
