We are overnighting in Madrid, having never been before. Will arrive around 7pm and need to leave for the airport at 8 the next morning. All we can do, really, is walk around and enjoy tapas for our single night in Madrid. Our family has three adults and one 13 year old. We would like a very nice hotel (but not The Ritz!!) in a lively but not crazy neighborhood. In Parisian terms, more St. Germain des Pres than Latin Quarter. Our travel date is a Saturday in early April. Help!!!
