Portsea Haven was perfect for my needs. I was in Portsea for a wedding, so the location close to the Portsea Hotel was ideal. Also, the area is really quiet.
The property is close to the beach but I must admit I did not test how convenient access was. There are several apartments (8 in total I think). #1 is close to the road, #8 closest to the beach.
The instructions provided to access the property were clear and I had no problems getting in. There were plenty of manuals and instructions for the various electrical appliances inside and also some information on local attractions.
Other reviews have commented on the bins. There are lots of them(!) - several for rubbish and for 2 different types of recycling. I was a bit unsure myself at first, but the loss of the bins actually tell you which is which.
