The place is exactly as advertised, but no more. If you're looking for a bed and a shower with the option of cooking and doing some laundry, you have it! But expect to bring or buy all the soaps (laundry/shampoo), condiments, and foods.
The public transport options are a bus stop just outside the building with a few bus lines to tube stops, two additional tube stops within a 10 minute walk, and a Local Rail station also about 10 minutes. All really great, and in an interesting, vibrant neighborhood.
Groceries are easily had, a Tesco Express being no more than a two minute walk and on the way from the Whitechapel tube stop. Yum yum Jaffa Cakes!
One thing to keep in mind if you are traveling in the summer: as a vast majority of buildings in London do not have air conditioning, it can get quite hot indoors, this flat is no exception. Because it is in a busy area, which is great for public transport, it is on a noisy street. So, you would either have to shut the windows and have a hot living space, or open the window and wear earplugs at night. Noise from the neighbors living in the building was very minimal, however!
Use of the washing machine was greatly appreciated, it made it so we could travel lighter than we would have and do small loads of laundry every day or two.
