Location, location, location, right on the Plaza Mayor with views of the daily activity, street performers, cafes. The Mercado San Miguel (great for tapas), just a few blocks away.
The apartment was lovely and, since the bedroom and en suite bathroom are at the back we did not have any issues with noise. As we were traveling without a phone we were delighted that Olivier was there to greet us when we got in from the airport (the apartment was within walking distance to both stations and easy to find). As he works as a translator, communication was easy and he provided maps and tips that were invaluable.
We woke each morning to the table being set and our choice of breakfast items. Really enjoyed our host and our stay.
