Javier was a fantastic host, met us in person at the apartment and gave us his details should we need them. Spoke excellent English.
The apartment is in a great location just over the bridge from the old town, a 5 minute walk to the main shopping strip, and about a km from the Guggenheim. There are bars literally on your doorstep, and while there is some noise in the evening it was nothing to stop a weary traveller dozing off.
