It's one way of getting reviews and I am sure people have done this.
There are a few things that may be stopping people booking your beautiful house.
First - you have a 29 night minimum stay - that means you are really looking for long term rental. Would you not consider a family who wanted to use it as a holiday home for a week?
Second: you have a set price of £195stg per night - which is fine if you have a party of 6/7 people. However, would you consider a lower base price (say for 4 people) and then an extra £xx per person for guests no. 6 and no 7.
The combination of these two would open up your property to a much wider audience.
