Elizabeth's place is superbly located! The 55 bus picks you up practically at the door, otherwise, it's a mere 7-minute walk to the Poble Sec metro in one direction or a 12-minute walk to Plaza España (one of the 2 hubs of life in Barcelona) in the opposite direction.
Her place is immaculate and the back yard is a lovely place to have your morning coffee or chill after a long day of sightseeing. All the amenities you could need are available and there are all the shops you could require in the neighbourhood.
