There were pluses and minuses to this flat.
Plus: Location was very convenient to transit (Tube and bus stops) and easy walking distance to pubs, restaurants, small supermarket, newsstand, etc. Plus the Museum of London. Flat was clean and the right size for two people, with decent kitchen equipment. Missing lightbulbs were replaced when we arrived and an extra sheet was provided.
Minus: Very noisy location, which became a problem in warm weather when you need to have the windows open. The only quiet night was Sunday. (This would be less of a problem during the fall and winter with windows closed, but trucks and buses go by all night long.) Also, people smoke outside and the smell comes right in. We stayed two weeks and the sheets and towels were not changed during that period - be clear about what is included in the price if you want this.
Finally, if you are coming from out of the country, make sure that you can contact the rental agent if no one is there...
