My husband and I and two adult sons stayed in this flat for 3 weeks from January 21 until February 11, 2016. The flat was comfortable and in a very convenient location. The bus stops were right outside the door and the Surbiton train station a five minute walk. It was very convenient to take the train to Waterloo station, about 25 minutes.
My sons and I often walked into Kingston. There is a lovely scenic walkway along the Thames into Kingston, a short walk from the flat. Waitrose was less than a 5 minute walk and Sainsburt's was also easily accessible. My husband has mobility issues so he would cross the street and take a short bus ride into Kingston and meet us there.
I would highly recommend this flat for a vacation base.
