Three families stayed at this property for four nights and we had a lovely time! The loft area was great for the kids and the foldable crib was a huge help for our 2 year old. The yard is large and fenced in, so the 2 year old had a lot of freedom to explore. There is a wading pool and two grills (one propane and one charcoal) to enjoy and you're just a 2 minute drive from a grocery store.
The owner is very kind but takes a while to respond to messages, sometimes requiring multiple messages before I received a response. The washing machine broke during our stay and I never received a reply as to whether or not she got the message. The only other disadvantages are the location: it is a drive to the beach, you cannot walk there. It is also far enough inland that mosquitoes are a big issue when you're outside. The last issue is there are only three bowls in the house. So if you have several kids who all want cereal, you have to get creative with the dishes.
Other than those hiccups, everything was great! If I visit Bethany Beach again, I'd look into renting at this property!
