We stayed at the coach house recently. There were 5 couples and two babies. The space was just enough so we wern't treading over each other. The fridge/freezer and pantry was a good size for all our food. It didn't matter there was only one TV as we were too busy catching up with friends, playing board games or reading. The bbq hut, hot tub and sauna was just amazing, this is where we spent most of our time; Drinks, roasting marshmallows and bbq food with music, we couldn't ask for much more! The house isn't overlooked and there's plenty of parking. The coach house is local to small towns and tourist attractions.
However, the house would benefit with a downstairs toilet, the wifi connection was very poor, we had to pay extra for towels and robes but some of us brought our own. There was an issue over giant flies coming in the main bathroom but the owner soon visited and sorted the problem (he taped over the air vent with sellotape).
