In short, we had a wonderful vacation staying at your apartment - the location wasn't just good, it was exceptional. The apartment was comfortable and Sandro/Alessia's suggestions for dining and site seeing were very useful.
The neighbourhood is safe, close to many good restaurants, tapa bars, grocery store, fresh produce market and many many historic and cultural sites. These are all within reasonable walking distance (my wife and I are seniors). With any city centre location there are some extra noise levels. Bus and train terminals for excursions throughout Spain are within walking distance and the international airport is a 15 minute train ride (3 euros).
