This apartment couldn't be more central. It has a lovely balcony overlooking the marina with a view of the sea and island. It has two bedrooms and a reasonably sized living room. Communication was good with the host - which happens to be the hotel/restaurant a couple of doors up. Have given 4 stars as there were a couple of niggling issues and WiFi wasn't working during the time we were there. The host did allow us to use the nearby hotel WiFi.
Otherwise, if you are looking for value for money, in the centre of L'Estartit, with a nice view and restaurants all around you - then this would be a solid choice. Note that there is a small carpark behind the building about 50m away which the host will allow you to use to unload/load your car on arrival/departure. You can then park in the beach car park for free, or pay in the marina car park just across the road.
