No one ever complained about the smell in the house; This is an old property, built in the 1920s and some sign of the time is to be expected even with the recent remodel. You and your family stayed 6 days, and never even considered opening windows; Of course, it will "smell" when 4 people stay in the 600ft2 for a week with their belongings and waste. The cottage is properly maintained and inspected regularly, new bedding and towels regularly provided. Yes, it's a bit small for a family with teenagers or grown ups but it perfectly fits 3 adults or a family of 4 with smaller children, as stated.
As for the jacuzzi, you missed to read the house rules before you decided to rent and once you booked; it clearly states that jacuzzi can be used upon request, and I did allow you to use it once my front house guests left. Read the reviews below, and you will find that I am very happy to please and share with my guests, especially the jacuzzi when requested upon the booking.
I am committed to sharing my home with people and strangers who are using AirBnB because they prefer the comfort of home away from home, and do not expect hotel standards. I love to please my guests, and am happy to refund if my home doesn't match their expectations; but you decided to stay all 6 days and I tried to accommodate you, even treat you with a hefty gift certificate to a reputable local restaurant. However, you even found a reason to complain about the restaurant. Clearly, this shows that you are hard to please, and you should probably stick to a different kind of accommodation.
