We (3 friends from Germany) have enjoyed the accommodation at Milena and her family. The room is great and has a separate bathroom. We are happy to come back for a stay in London. The house can be reached from the Tube on foot in 10 minutes, so really not a problem.
In addition, located on the way to the house directly a pub (The Pipe Mayor) we can only recommend. Prices are absolutely fair compared to London City. Must you visit her absolutely. Another tip for London travel, visited the "LEON", when ye recover from Fish and Chips times. Food is excellent and the prices are low.
