I stayed in the household at Greene House for 4 nights. I have to say, first impression wasn't great - I had some trouble finding the place even though I'm a local in London - the building block is strangely designed, typically for London. And just when I finally found it, the sight of a council block terrified me and when I tried (unsuccessfully) to get the key out of the lock, it started to rain and my phone had 1% battery left...
But when Sarah arrived (I didn't wait long) and let me in, I was pleasantly surprised. It is a council flat but the bathrooms are refurbished and the household is very clean. I stayed in a micro room which was fine and there are bigger ones available in the flat for more than 1 traveller. There is pretty much everything you need there. The gas oven is very vintage but working. Microwave, hairdryer, wifi,towels, everything is available. The other occupants / travellers were really nice and Sarah was very welcoming.
The place is walking distance from Bermondsey St and Borough Market which might be the best places to hang out in London. Good place to crash for a few days stay in London.
