First of all, the cost-performance ratio is not comparable with Europe where you get a high standard, modernly furnished apartment with the newest up to date tech gadgets for 350$/night but that seems not to be the standard in the US.
However, we had a good stay at the apartment. It was very helpful that the apartment is well equiped with beach staff. Also the area where the apartment is situated is a big advantage of the apartment.
Communication was fast however, way to much Do‘s and Dont‘s and way to much mails. On vacation we want to relax and may get one mail with the most important things but not that many mails and additional information on paper.
Moreover, the furnitures and the tech gadgets like TV are quite old. At some places the apartment looked a bit filthy.
