Sam's place was clean and in good location to access public transportation, especially the Underground. This made getting around London easier. The apartment is about 20-30 mins by the Underground to most of London main attractions. Knotting Hill is a beautiful and quiet residential neighborhood. This means restaurants and pubs do close rather early; 2200-2300. And the Underground stops around midnight, so you have to use the sparse bus after that time.
Sam is a good host, he was courteous, friendly and prompt with communication. I really enjoyed the suggestions for the local restaurants and pubs. The Portabello street Market was also worth the visit.
The room I stayed in was clean and had a comfortable bed, I however feel it's more suited for one person, 2 might be a squeeze especially considering luggage.
