RIU FLORIDA BEACH HOTEL -

This hotel is located on Collins at 31st St. I stayed here as a
young kid in 1970s when it was called the "Sans Souci" hotel.
This was architect Morris Lapidus' first MiMo era hotel, built
in 1949-1950, a few years before his famous Fontainebleau or
Eden Roc hotels. The "Sans Souci" hotel building is still there
today, but is called the Riu, but the outdoor pool area and
grounds have been redesigned from what I could tell when
recently walking the property. I have not stayed here in many
years, so cannot review the rooms, but many reviews say the
rooms are in need of refurbishment. This hotel would be a long
walk to the South Beach area.
