A hot one!
We visited Prince Edward County during the draught and heat wave in August 2016. It was over 35 degrees everyday and there was no A/C in the house. We didn't sleep at all because of the heat so had to move to our friend's rental and a hotel during the week to get sleep and be comfortable. The shower curtain and bath mat needed to be changed because they were dirty. The house is a nice size for 4-5 people (only 1 bathroom) It's a nice cottage in a peaceful secluded area. Probably best to stay during a cooler season to have an outside bonfire and not be hot. It was close to Wellington so it made it easy to get to town and get groceries and/or go to a restaurant.
A lovely three-bedroom cottage is in the heart of PEC's wine country
