We stayed on this lodge park before and really enjoy it for its location and easy access to walks and the Botanic garden. Chestnut lodge is well equipped and maintained, we would certainly recommend stating there. Only issues was we could not get the internet to work which wasn't a big deal since we were out most of the time anyways.
This is a modern house in a secluded location on the banks of Ascog loch. We stayed for 3 nights with our 3 teenage sons. House is practical and warm. The only negative point is that the lounge area is small and only sits 3 people comfortably. I quite enjoyed not having WiFi and only the occasional 4G signal, the boys not so much.
