Nice little no-frills stay near the Queensway station with easy access to bus service at the end of the street.
There is a dehumidifier at work in the hallway, but it is a basement unit in London, so expect to stay on top of your allergy meds if you're sensitive to the slight smell of mildew etc.
Overall, as long as you go into the deal with an understanding of the situation, it's a great value. Ali is also very honest and upfront in the rental agreement. Definitely recommend this place for the budget conscious traveler.
