I and two friends have an overnight stop in Madrid and I need some info on a good hotel. I've been in most of Europe, but never in Madrid, so I don't have a clue where to stay. Are we better off getting an airport hotel or going downtown? How is the public transportation for going downtown? Even if we stay near the airport we may want to go into the city a bit. We are looking for a good price, not luxury! We arrive Sunday, April 6, at 6:10 PM, and leave April 7 at 12:05 PM. Most of the budget hotels I checked only accomodate 2 guests per room. Any and all advice will be welcome. Thank-you!
