House swap? Central London Georgian townhouse available for 2019

We are a family with two kids aged 6 and 3 years old, looking for a house swap near Stanford. We have been here at Stanford since January and are currently renting out our house in London, UK. However, we were wondering whether anyone would be interested in a house swap for 2019?? It is a beautiful Georgian period townhouse on four stories (c1700ft2), 3+ bedrooms, 2.5 bathrooms with a large backyard. Centrally located in Brixton- it is an easy bike ride or short commute to all the major London university campuses. We are keen to stay within an easy commute from Stanford, are flexible on timing and are happy to consider any offer! Thank you
