The apartment is spacious and very centrally located, with a beautiful view of the canals and very near to shops and restaurants.
It is simply furnished, but has everything you need.
Even during the highest temperatures southern France has EVER experienced (June 2019), it was bearable, if not very comfortable in the appartment.
I can recommend it.
Tip: take the bus and have a meal in a restaurant by the port in Marseillan.
