Our family (4 adults, + kids age 4 and 1) had a lovely vacation here; this was easily the nicest beach rental we have ever stayed at; and the thoughtful communication with the owners was top-notch hospitality.
House was great for our group - gorgeous master suite for me, my wife and our 1 year old, and nice sized bedrooms for 2 other adults and our 4 year old, sharing 2 full baths between the 3 of them. The house is also really nicely decorated in beach themes. Kitchen had everything we could have wanted, and the new grill with grill tools were great for cooking out and dining al fresco.
Array of board games was a benefit with the kids - got to play Trouble! for the first time since I was a kid myself on a seaside vacation :-) Having both a living room on the main floor and den downstairs was also great, so we could enjoy movies downstairs without waking the kids upstairs.
Location was very convenient overall, on a quiet street a couple of blocks from the highway. Easy walk to a good coffee shop and a good beer/wine/cigar store. Easy to drive to a huge Publix supermarket to stock up on food for the house or the beach.
Also nice that both beach chairs and beach towels were available. I think it would be walkable to the beach if you were committed to it and didn't have a lot of stuff. But with small kids and a grandmother, a cooler, beach umbrella and stuff, then having the option of using the parking lot right next to the beach was very convenient.
Overall we loved our stay and really appreciated our hosts, who were proactive in sharing information, answered all our questions promptly and shared some great local dining tips when we asked for them. The house is great - and the first rental I've ever stayed in that made me think we ought to step up our game in beautifying our own home. Literally our only issue is that we should have booked a longer trip than 5 nights! Hope we'll be back in the future.
