The honest truth is this:
Good - location is great. 3 minute walk to beach. Pool area actually a little nicer than expected. Away from town but still close enough for kids to jump on bikes and ride into town. Sidewalks everywhere. Very convenient. The only downside was the hotel nearby with trucks coming in and out all night. Also neighbors across the street had a large crew extremely drunk and loud all weekend and late into the night, but that can’t be avoided.
Bad - I read some reviews that said needs updating, which is fine, but it was actually quite dirty. The owner has clearly not invested much in the upkeep as things are just falling apart from age. But worse is that things were quite dirty. Examples: many dishes and pans needed to be rewashed, the silverware tray was filthy, the nice little built in bar area looked like a scene out of The Munsters with everything covered in dust, and the little decks looked like they hadn’t been swept in over a year, and the little glass table just caked in dirt. These are just a few examples but you get the idea.
My advice to the owners - invest a little more in a better cleaning crew, and just patch up a few things that are falling apart. Appearance and perception would go a long way in this becoming a really great rental. It’s not inexpensive for a place with no beach view, so spoil your guests a little.
Overall we had a great time. Everything was very convenient, and location is great. Just step it up on the amenities and appearance a bit to make it even more appealing. It would surely pay you back for that small investment.
