Darren was great with communication prior to arrival and then left us to it to enjoy the holiday. The flat itself was really clean and had great amenities.
We were with a 7 year old, its about a 15 minute walk to the nearest underground which was fine for us but may be too far for young kids. Buses right on the doorstep though.
Only slight downside was the thin walls in the flat to the upstairs flat. Thankfully they were fairly quiet but you could hear everything.
The area is quiet as well. Great place to stay for a base in London
