This location is unbeatable! It was very easy to get to the apartment (from Aeropuerto Barajas) as there is a metro station close by (its like a 3 min walk). It was easy to get around and I felt safe walking in the area, even at night. Puerta del Sol, Plaza Mayor, Gran via as well as many restaurants are a short walk away. The apartment is extremely clean and quiet and the hosts are suuuper friendly, helpful and made me feel extremely comfortable. I'd definitely stay here again. Just keep in mind that there's no elevator in the building and this is on the 4th floor. This stay is definitely worth it though!
