I recommend this tour to everyone! It's a great way to experience Madrid nightlife with a knowledgeable guide who shares what he's learned on his own. Our particular guide, Paul, was thoughtful and smart; he shared historical information as well as tips for enjoying bars, drinks, and free tapas and rubbing elbows (not just a metaphor) with Spaniards. He asked for our input at many points on how to tailor the tour to our interests. We experienced a variety of tastes in drinks (cider, wine, etc) and food. Paul showed us some of what made him fall in love with Madrid (6 years ago?) and decide to stay. We used his tips on subsequent nights to enjoy tapas and nightlife all over again.
