I've been at Carlos' place for 6 nights and I really enjoyed my time in London. Room is comfortable with two double bed and private use of the bathroom, clean as all the house is.
Position is really good as it is in a very nice area, 10 minutes walking to Canary Wharf Underground station.
Carlos is a super and lovely host, he made me feel home, so welcoming, always caring (also gave me accurate directions to get there from Stansted) but also being very discreet at the same time! Highly recommended, no doubts!
