Very nice apartment, really luminous, spacious and welcoming. Great bedding (which is for me very important as I am tall and not very light). Next to underground and buses, nice shops and restaurant in the neighborhood (Brixton Market is lovely).
if you want to spend some days in London, I would highly recommend Tomas apartment.
We were 2 adults and 3 kids, and that was perfect for us.
If we go back in London, I would go there again.
(But don't try to come at six, the sofa is too small.)
