Overall judgement of our stay at Tope's place for three nights: pretty good.
The house is as small as expected (considering he lives alone), yet not a great problem,as you're supposed to visit London rather than staying at home! The bedroom is quite cosy and the bed is comfortable enough to let you forget the noise of the trains passing; there's an armchair and shelves and hangers you can use to put your stuff on.
We could store things in the fridge, which turned out useful.
As for the cleanness, the house is pretty messy, but generally clean (he fortunately gives importance to the toilet's conditions)
The house is in a very good position, at walking distance from 2 metro stations and Southbank. The area is safe: I can mention as a proof our leaving the house at 5am to reach our bus at Waterloo station. I didn't expect that it would've been safe for two girls walking in the streets at that hour in the morning, but Tope gave us good advice, telling us it would've been ok.
As we spent most of the day out, we had just a couple of chats with Tope, who still turned out to be really nice and good to talk to.
