It would be hard to have a more central location to stay in Madrid. Just a few minutes walk from the Plaza del Sol, there are plenty of good restaurants and shops within a minute or 2+ a nice little 24 hour grocery store. Oscar was incredibly helpful and super fast to communicate. The apartment was clean and had everything we needed. The only thing you need to be aware of is especially on the weekends it is pretty loud outside since it’s a pedestrian walkway until pretty late like two in the morning and the curtains don’t fully block out the light and the flashing lights across the street could be a bit bright. Nothing that an eye mask and some earplugs wouldn’t take care of! Highly recommend.
