John's apartment was the perfect size for our family of 5! We have 2 sons, 23 and 19, and a daughter, 15, so it was important that everyone had their own space after long days of exploring London. It was comfortably furnished, with lots of pillows and towels for all of us. The main living area is open and airy, and was great for playing card games in the evening. The only drawback in the apartment was that the shower was a little short for us. Something to be aware of if you're taller, but really a minor issue compared to all of the positive aspects of the apartment!
The location was just perfect! Far enough outside of the city to be quiet in the evenings, but with easy access to transportation to the center of London. We purchased a 7 day Oyster card and usually took the 137 Bus or 452 Bus into London (stop is about 2 blocks away), then switched to the Underground to get to our destination. The Queenstown Rd. Station is a few more blocks away. The Citymapper App made it easy to navigate London Transit.
John was very responsive to all of our communications and was very accommodating to our schedule -- an excellent host! He gave us great tips for eating, travel, and local grocers. Choosing to stay at his place contributed to the success of our trip, and we would definitely do it again!
