+++ Could be better +++
I stayed at Andrews single room for 11 nights.
The appartment ist well located, very (!) close to Haggerston station with great connection to the City.
The room is so far mid-level clean.
Unfortunately, the mattress of the bed is very bad, but Andrew promised to change it!
Main problem is, that Andrew rents three rooms, so there is a continuos change of the "flatmates", and all in all you kinda have a "hostel-feeling" (doors slammed, crazy "neighbours", some treat the bathroom not so well)
Another thing is you have to be clear you have no access to any kitchen and the fridge in the room is so loud, you either cannot sleep or keep things cold.
All in all, it might be ok for a few nights, but there a better places in London.
