I stayed in the Augusto's flat with 3 other friends and our stay was perfect. I say this because the apartment is spacious and comfortable, complete with everything you need for cooking, very clean and tidy, all this at a very low price!
The metro is just a minute walk from the house as is the supermarket. But the real discovery was the fascinating and lesser known Greenwich which can always to be reached on foot.
Finally, communication with Augusto, before and during the trip, was very simple since he also speaks Italian. In other words, I highly recommend staying at Augusto's flat.
