The pros: Joe is a very welcoming host, a true londoner who's willing to share a ton of useful tips about the greatest places. We had the opportunity to discuss a lot of subjects with him as he definitely seems to be an open-minded person.
The flat is also very conveniently located, about 150m from the Stockwell station from which the centre of London can be reached in less than 10 minutes.

The cons: the flat is not clean, with the worst part being the toilets and the bathroom. We also had to ask twice for Joe to provide the towels on our day of arrival; he did bring one, after 10pm. No toiletries of any kind were provided.
I understand that this is a cheap accomodation according to the London standards, but in our opinion the minimum requirements in terms of cleanliness and service were not met.

Unfortunately the cons negatively influenced our Airbnb experience this time. In our opinion, this place is not suitable for a young couple seeking a simple but clean place to stay for a few days in London, and that is why we can only give two stars for Joe's accomodation.
