Great place - would have loved it even more if the price was lower, but we ultimately have no complaints about our stay. This apartment is Damien's personal home (he told us this himself, and it was also evident from the collection of books on shelves, home theatre system, well-tended plants, cupboards partially filled with Damien's clothes, etc.), so it was a beautiful and comfortable space to live in, and we could tell that he put a lot of personal care into maintaining the place. There were two rooms with a double bed each, as well as a sofa bed in the living room, so it was sufficient room for myself and three other friends. The apartment is a straight road down from Waterloo station, about 5 to 10 minutes away on foot.
Host-wise, Damien was a very gracious host and took the initiative to contact us to help provide information about our stay and London in general. He was also quick to respond to our queries, and accommodating to our requests. For instance, although we could not settle into the apartment earlier than 3pm because Damien needed to clean it after the previous group left, he was relatively accommodating to our schedule and flexible about meeting us there any time after.
Overall great stay, and we would come back again if we visited London in the future.
