The room at Muk's place is upstairs in a small house in eastern London and has everything one needs for a shorter or longer stay. Muk really paid attention to the details: there are some guides, there is a converter for if you bring devices with a European plug, there are toiletries and a towell, etc. The bed is comfortable and coffee & tea are available as well.
The room at Muk's place is located in eastern London, just a few minutes on foot from London City (LCY) airport. Do note that there is not really anything close by (restaurants, shops, etc.) or maybe I just didn't look good enough. I used the convenience store in the airport for some small shopping.
I can sincerely recommend a stay at Muk's place, especially if you don't care too much about being in the center of London.
