Just as the other reviews suggest, Sam was the perfect host. She was there to welcome us and allowed us to check in early. She was very friendly and welcoming, and wanted to make sure we were having a nice stay. Lovely person!
The place is small but very nice and clean, and most of all, quiet. Not easy to get in central London, especially right next to a tube station!
The private kitchen was very pleasant, and there were some things for us to use when we arrived (such as tea, butter, etc.).
I highly recommend and would stay there again.
One small note if you come from the US or Canada: king sized beds in the UK are similar in size to North American double beds.
