We are bringing my parents along for a visit to London and a friend lives in the Kensington area so suggested we try to stay nearby. First, how convenient will we be for sightseeing, etc. since this is our first time here? We would also like an area where we can walk to restaurants or bars. And any properties you would suggest that work for 4 adults -- we would prefer two rooms, possibly breakfast included or a large suite. Thank you.
