Ditto on:

1. Saturday's dust

2. Tapas and beverages at an outdoor cafe is as relaxing and pleasant an experience as you will find in Europe.

3. The "J" service on the route was superb .... had the same crew on Friday and Sunday and gave applause certificates to the 4 up-front folks .... which they all appreciated

BTW, I highly recommend Hotel Preciados --- excellent rates, good breakfast, free wireless, VERY convenient to two Metro stops, plenty of cafes in neighborhood ... http://www.preciadoshotel.com/ingles/index_en.html
