The property just missed the full complement of stars because problems raised by previous users had not been corrected. The front door lock was very temperamental, and the washbasin taps in the bathroom were very loose, which if not corrected could lead to a disaster. The kitchen taps are obviously coming out in sympathy with their posher brethren, but at this stage were only slightly loose.
Parking is a problem which should have been clearly explained in the initial information rather than left to be discovered in the information book left in a sideboard drawer.
Otherwise the property was very clean and exceedingly comfortable.
Attention to the points detailed above will raise the score to 6 out of 5, and you can't get better than that.
