First off, the accommodation is as listed in the profile. Serena is gracious, friendly host and made staying there very easy. Of particular note is how close both the Vauxhall Underground and the Overground train lines are ind addition to the bus lines; getting around London from Serena's place is VERY easy. Aside from the ease of transport, there are numerous shops around where you can pick up any incidentals you may forgotten. Also, the WIFI works great.
I can, and do, recommend Serena's place without hesitation.
