First of all, let me say that the owner Mark was wonderful and helpful before and during our stay.
The unit itself (510) was clean well stocked with kitchen supplies, bathroom supplies, and even beach supplies like chairs and umbrellas. I'm not sure how old the Sandcastles condos are, but judging from a glance inside a couple of the other units through windows I'm guessing it's been around for many decades. This particular unit has been almost fully renovated with the lone exception of the showers/tubs in the bathrooms, which we appreciated.
Though the condo complex is aging, it seemed clean and well maintained. The elevator stayed clean all week as well as the pool/spa and the grounds in general.
Now I'll go a few issues we had with the property. These are all fairly minor.
The first issue with the property is the poor sound insulation between the floors. There was a notice posted inside the elevator warning about this. Apparently it's due to the "dense concrete". You can literally hear a pin drop from the unit above you. People scooting chairs around is particularly loud. Thankfully, the sound travel seemed limited to actual impact with the floors. We couldn't really hear much in the way of televisions or voices from the units above or around us. If you have an extremely inconsiderate owner or guest staying above you who ignores the warning/notice in the elevator, it could put a real damper on the ambiance. I suspect you could largely or completely avoid this issue if you stay in a unit on the top floor (7).
We stayed in the South building, which is a long rectangular shaped building with the short sides running parallel with the beach. The elevator for the South building is on the opposite end of building from the oceanfront units, so to get down to the beach you have to walk the length of the whole building, ride to the bottom, and then walk the length of the building back again. We wish the elevator was more convenient to the beach side, like the North building had.
There is only one way in/out to/from the property and no traffic light, so turning left can be a bit of a hassle at the business traffic times. Fortunately the places we went to were to the right.
Finally, I think it would be nice if the owner would invest in smart TVs, at least for the living room. We did appreciate the good WiFi and that the (Spectrum) cable service was HD.
Great stay overall and will consider this unit again in the future.
