Very friendly and helpful staff. They even put out breakfast early for us so we could eat before our early fight! Would definitely recommend!
While The Walrus is in a convenient location to get to anything you want to see in London, it is also immediately next to the Waterloo train/underground lines. You could literally throw a rock out the bedroom window and hit a train. This means that while the train is running, it is very noisy. Otherwise, I would have rated it higher for location.
Innkeeper was very helpful and courteous. Food was delicious and the portions generous. Would definitely stay again!
