I spent 3 nights in Ruben's place in Madrid, and it was the best choice I've made for my trip. My family(3 people) arrived late in Spain but he waited for us and showed his beautiful place. There was everything we need just as at home. The location is perfect too. It's near the Plaza Mayor. Actually I should say it's at the one of the entrance! My parents are around 60 but we could visit almost of all popular spots on foot. The room is exactly same as it shows on the pics here. If I have chance to visit Madrid again, I will choose Ruben's place again without hesitation. He was always there for us when we texted him for questions and recommendations. Gracias!
