I believe there were 4 units with an office on the steepled top floor.
We stayed in Sebastien's unit - the white leather modern one, top floor to the left when viewing from the street.
IIRC, there were 4 plastic lounge chairs in the basement, with no designation which unit they were for. I don't recall an umbrella.
At night, there were mosquitos, but no problem during the day. I def recommend keeping the rolling shades down at night for security.
Have a great trip!
