We stayed in this property for a week over summer. Overall, the house was very nice and well appointed - there were a few cleanliness issues upon check-in, but the management company were very quick to contact us and rectify the situation.
We had 4 adults and 4 children stay in the property - the layout and rooms were great. Agree with other posters that the front bedroom is basically fully lit 24 hrs a day - there are 6 windows around the top of the room which allow moonlight, streetlight and of course sun in. We had kids, so a lie-in wasn't much of an option anyway, but beware if you're looking for a more relaxing stay!
The pool was fantastic for the kids, the outdoor area could do with a few more chairs (there are only 3 seats and 2 loungers), but we made it work.
Walk to the beach is not 300 yards! Maybe from the exit of the development - but it's a hike to that. It's definitely walkable, but more like half a mile. I think there may have been a shuttle, but we didn't see any.
A few of our party used the pool facilitates at the nearby hotel and enjoyed them. Overall, the property was nice and the management company very keen to ensure we enjoyed our stay.
