Madrid was my first solo trip and although I was a bit skeptical when I arrived, I soon realized I was in a safe place and near everything I wanted to visit. The building is secure and the apartment has a floor to ceiling patio door that blocks out all the outside noise as you have people walking outside all night( no one sleeps😳😁) I just wished I had started exploring other areas before my last two days. There was so much to do! And 24 hour stores right down the street as well as restaurants right there, although I only ate croissants in the neighborhood because there were just too many other choices.
