How long can a Hungarian Vizsla be left at home alone??? (occasionally, not every day)?

my family is looking to by a Hungarian Viszla as our first dog, we live in a large house with a large garden and 3 large parks and open spaces near us, we would happily walk our dog 60 to 80mins a day. whilst there is someone home most of the time, occasionally the house is empty for half a day (approx once every 2 months), is this too long for a Vizsla. and if so what is the maximum length of time it could be left alone?
