It is lovely but things I'd be thinking about.
Are the bathrooms ok for your family? There looks to be a smaller one and a larger one both upstairs, is that ok for you with 2 teens?
Is there any safe outside space for the animals? It looks quite urban. Do your cats get out? Can you walk the dog nearby?
Is it noisy? Like I said, quite urban looking, close to the street.
Schools for the teens? Does it mean a change.
Do you have the money do to the things you want, and if you do, will it retain/add value? The kitchen looks a bit dated but useable, how urgently does it need a new one. It could be nice to open it up a bit into the meals area to make a huge space, if that were possible.
