We had a really amazing stay here as 2 adults and a toddler, we were supposed to have another couple staying as well but they couldn't come, but there would have been plenty of space for us all. James and Maria sorted out a 'pack and play'/cotbed for us which was really great as saved us taking one on the plane!
The stairs are a little steep and could do with a gate at the top if there are kids there (we used a chair at the bottom of the stairs which worked fine), and you'll need to be aware of little people and the steps outside too. Outside space was lovely to have as well though, especially as it was really hot!
The bed in the main bigger bedroom wasn't the most comfortable, but the other one was fine.
A really lovely stay in a beautiful house in a great location, clean house, well stocked. If I was coming back I wouldn't hesitate to book the same place. Maria was also really helpful.
PS. If you do come with kids, Dufferin Park, which is about 20 mins walk away is a great enclosed space for kids to play in and really well shaded! There is another park closer but it isn't as well shaded in the heat. Also the aquarium was great fun.
