We had a great time staying at Jonathan's place with our 1 year-old. It's beautifully decorated and really comfortable, they clearly have an eye for quality materials and products. There was plenty of space for the 4 of us, and our son was over the moon being able to run around the garden and play with their son's toys.
The location is great for walks along the river to Richmond and decent for trains into town, and for nights in there's a dangerously well-stocked honesty bar.
We'd definitely recommend it, especially to families with small children. It felt like a home away from home, and Jonathan was really helpful, always just a text away. We won't hesitate to book it again if it's available next time we're over.
