My friend and I stayed at Richard's for 6 days. He provided us with a London tube map and a flat tour - as planned in the description on the website. He let us use the kitchen, even if we actually never did, since we were almost never home. The house was very clean and had a pleasant smell of incense. The room was not very big, but it was cosy, warm and very nice to look at and live in; the bed was very comfortable, we were given two fresh towels each and the power strip allowed us to charge several devices at a time (Richard provided us with an international plug adapter). As for the bathroom, it was small but practical. We had our own keys and we were able to leave and come back at our own hours, as we liked.
The flat is situated in the 3rd zone, which is not far from the city centre, in fact using buses or the DLR trains you could reach zone 1 in 30 minutes, give or take. There are also night buses/24h buses passing by (i.e.:474) , if you fancy staying in the city a little longer sometime. The bus stops are 2 minutes away, whereas the DLR station Cyprus is 3 minutes, 4 tops, away.
The neighbourhood was and felt very safe, quiet and pleasantly/typically English, just like you see them in the movies!
If you need to shop for groceries, there is a little shop just in front of the Cyprus station or a supermarket a little further (5 minutes walk or 2 minutes by bus), Asda, with a wide range of products and quality food.
Richard was a very good host and we recommend his flat to anyone coming to London.
