A typical villa with Loos's concept "raumplan" and typical details for Loos's work, like terraces and pergolas.
On this website is a good summary of the villa. On the ground floor is located the entrance, nowadays used as the cashier. Behind it most of the space is used for the living room. On the first floor are placed the sleeping room, further living rooms, a bathroom and a toilet. A big terrace is accessible from here. On the second floor are further romms and the access to the terrace too.
The caretaker’s flat is located in the basement level. Today, the entire house has been furnished and presented to reflect the period in which the villa was originally built.
On the website are beautiful pictures of the interior.
