There are 4 options here, a converted garage called the studio, a house split into 2 sections and the gazebo at the end of the garden and right over the river. We stayed in the gazebo which is a spacious bedroom literally in a converted gazebo with spectacular views of the river, birdlife and a passing train! The room itself was clean and comfortable, tv included, bar fridge, fans and air conditioning and necessary insect repellent.
Downside for me was the need to exit the gazebo and use outside stairs to get to toilet and shower which in inconvenient in the middle of the night and whilst also clean, is not the nicest of bathrooms. I am prepared to concede that sitting on the deck watching the sunset every evening may have compensated.
