I’m hoping someone else will answer with more detail, but I can tell you what I know because they were being constructed during the years we owned an estate agency here. They were built as residential apartments, hence the name Residencial Virginia Oasis, but many were bought by foreigners as holiday homes / investment properties.
They are quite a way out of town – about 2KM walk. I gather many of the apartments bought for investment are long term let to local workers.
Are you asking as a place to stay for a holiday, or as something you are thinking of buying?
