Compared to other places in London, even this area, this place is cheap. The room is ok, the bed is comfortable, the location is good and convenient.
If this is all you need, take it.
What you will to have to put up with: Communication only via email, so make damn sure, you will have a reliable mobile internet connection, even if from out of the UK, otherwise no way to ask something when you are there.
Once in, no sign anywhere reg the in house WiFi! The "Bathroom" consists of 2 small stalls w toilet (one of which with a door I wasn't able to lock) and a minuscule sink with no space (hooks, shelves etc) to put down a toothbrush/towel/bag and one small shower for all the tenants (8 or 10 I reckon). Didn't use it, so no comments.
In my room I could hear not only the next door neighbor loud and clear but also the ones 2 or 3 rooms down (radio, tv, nose blowing, burping, snoring, walking... you name it).
The TV didn't work (would have been nice to counteract the unwanted noise... ), neither did the heater (didn't need it though). Again, no way to communicate with the host, since I didn't have internet until I managed to find a "pay for" service.
Left the next morning, refund was no problem at all, which was good!
