My got it two years ago for our son and he loves it!  I purchased this house specifically for the attached floor and it has not disappointed... There are no seams in the floor or on the seat so I can hose it down or sweep it out easily.  It is also very lightweight so I can move it easily and tip it over to drain rainwater with no problem.  It is also roomy enough for my toddler son and one seated adult.  It has been outside for two years with exposure to rain, snow and late afternoon sun and there has been no fading so far.
