Our (mine and my boyfriend's) stay at Emi and Simons' place has been absolutely astonishing, it definitlely went beyond our exectations. The whole house is clean, cozy, bright and stylishy furnished, with fresh flowers in every room! Plus you can help yourself to their amazing espresso maker! Emiliano will provide you with everything you could possibly need, from plug adaptors and hair drier, to a lot of useful information, books and guides about London. Emiliano and Simon are definitely two lovely and helpful hosts!
Then, Brixton is a strategic place to stay, you can get to the centre in just a 15minutes underground trip, and the neighbour is very interesting and full of nice pubs and multi-ethnic restaurants.
So, all things considered, we warmly recommend Emi's place, it will make you really enjoy your stay in London!
(and, last but not least, the price is more than fair for the kind of accomodation!)
