We really enjoyed our stay in Debbie's flat. Debbie wasn't in London when we arrived, so her boyfriend showed us the flat and provided us with all the information that we needed. Communication with the host was helpful and friendly.
The apartment is clean, quite comfortable and fully equipped with new kitchen. Also, knowing the room sizes of other London flats and especially hotels, the flat is rather spacious for two people. I was travelling with a colleague at work, and one plus for us was that we could use the sofa bed in the living room as a second bed.
But I think what we enjoyed the most was the location. While the flat itself is situated in a rather quiet street, there are dozens of pubs, cafes, restaurants and shops around Upper Street, Islington High Street, Chapel Market and the Angel tube station - all within a 5 minute walk.
All in all, I would fully recommend Debbie's flat for a visit to London.
