Lyonel's place is a cozy apartment in a great neighborhood. Exploring Barcelona from here was simple. A short walk gets you to the Metro so you can see all the typical tourist spots if you want or bounce around to all the interesting and varied neighborhoods where you can feel a little more like a local.
I didn't spend a lot of time at the apartment, but it was comfortable and the location couldn't get much more convenient for what I wanted for my trip.
