my house is in La Marsa 15 minutes per feet from the beach (5 minutes by car) and close to all facilities. So when living in it, you don't even have to use a car unless going somewhere else :)
Public transports to Tunis downtown (medina, Lafayette, etc.) are 10 min max per feet.
In the house, there is:
A living room
And a terrace.
Make yourself at home :)
But no parties at night coz I have an old couple living next door.
