This was one of the best Airbnb experiences I've had. We are a family of four and the space was very comfortable for all of us. David had his housekeeper meet us at the place on time and was thoughtfully on the phone so he could translate. We had all the information we needed to have a great stay. The amenities were great - the place has a fully functioning kitchen with basics. It has a washer which can also function as a partial dryer which was very useful! We needed an extra bed and our housekeeper showed us how to fold out a couch and bought us extra linen within 30m.
In terms of location, this place is the bomb! It is in a quiet street off Gran Via - a very short walk from the heart of Madrid's city center. It also has access to quieter parts of town that were less crowded and great to roam around in when you want to be away from the crowds. We hit all the highlights of Madrid within 20m walking distance of the place. The furthest was Retiro Park, which is a 30 minute walk away or a quick €6 Uber.
If we come back to Madrid, we'll absolutely come back to this apartment!
