We had a great time staying at Miguel and Iaia's apartment. Checking in was super easy and, as everyone else has said, the handcrafted guide book was most helpful. Iaia was always available to respond to my questions and messages throughout our stay. The bed was soooooooo comfortable and we are very picky when it comes to sleeping away from home! It was also nice to have access to a washing machine since Madrid was the halfway point of our adventures in Spain. Best yet - the apartment is so perfectly located to all the major sights - no need for public transportation besides getting from the airport and bus station with our heavy bags. We bought a one-day subway pass when we arrived at the airport thinking we would need to use transportation to quickly access the sights but we quickly learned that walking everywhere from the apartment was much more convenient than navigating the labyrinthian subway system. Thank you both for a wonderful stay!!!
