We really enjoyed our stay in Madrid at Christian and Felix's apartment. There are a lot of artful decorations including vintage furniture and beautiful flowers. The location was ideal and barely 10 minutes to the main tourist area of Madrid. Christian and Felix were especially helpful with helping us figure out where and how to get COVID tests in Madrid which proved to be a very challenging experience that they helped us navigate. One issue was that there was construction in the building and a family with small children which made it difficult to have a restful sleep. However, this will probably not be an issue for future guests.
