Guy's place is very conveniently located for walking or for getting public transport around London. It was clean, quiet and overlooked peaceful gardens. It was comfortable for three adults to stay in (but might be cramped with a 4th adult due to a shortage of storage).
We prefer to stay somewhere with a kitchen so we can save money by having breakfast and cooking some of our meals, rather than eating out. We would have liked to have had more kitchen plates, bowls and utensils (for example, we only had two usable bowls for breakfast). There were also a couple of kitchen maintenance issues: no light bulbs in the fridge or cooker hood and a dishwasher that was broken when we arrived (when we tried to use it, it filled with dirty water that we had to empty into the sink). These issues were communicated to Guy but unfortunately not resolved during our 10 day stay.
Finally, a minor point, but the photos of the apartment should also be updated. Some of them show furniture that isn't actually present in the rooms.
Overall we had a pleasant stay and would stay again.
