My wife and I hosted a group of 8 for the 75th anniversary of D-Day. Lilli Cottage was magical. All the pictures are very accurate. The house is beautiful. It is only minutes on foot from restaurants, grocery stores and bakeries. The tourism office is literally a two minute walk from the house. The beach is also very close.
The owner of the house was very communicative. The time difference caused an obvious delay but I had some questions regarding the events for D-Day and Sophie was very helpful.
About the only thing I would make sure visitors know...especially if you have a good sized group...is the overall bathroom situation. One main bathroom on main level (sink and tub with shower) but the toilet is in an adjoining room and if you're 6 feet or taller, it will be a bit cramped. Every room had a toilet and sink in a small room. Toilet for #1 only though. The outside rooms which are separated from the house and accessible through the garden, seemed to be the best. We called it the Montgomery suite. While I wanted to mention the bathroom situation, it is a very minor thing. Overall the house, as I initially stated is wonderful and Sophie couldn't have been a better host. If you're staying anywhere near Houlgate, I would highly recommend Lilli Cottage.
