We only had 1 afternoon in Madrid and this apartment was in the perfect location. We were able to walk to Mercado de San Miguel, Plaza Mayor and Puerta del Sol. There were good restaurants right on the street where the apartment was located. The owner gave us good information about getting transfer service from the train station and then to the airport the next day.
The apartment was very nice. 4 bedrooms with living room/kitchen in the middle. I would have liked to stay longer. Hopefully, there will be a next time.
