Tom and Mary's B&B was the perfect place for our group of 3 (offering 2 bedrooms + living-room with small kitchen and terrace). It is confortable and clean. Everything was exactly as described and we enjoyed our 2 nights stay there a lot.
Mary made us feel very welcome and accomodated our needs perfectly when we asked about the laundry and wanted to use the bikes.
The location is great too, quite close to local point of interests (like the Nambung National Park and its Pinnacles). Overall, it is a very good alternative to motels/hotels in Cervantes if you plan to visit the region.
