This is a great apartment. Keep in mind, it is on the 5th floor of a 5-floor walkup but the location, cleanliness, convenience, and history of the building make it worth the climb. I would definitely stay here again. It's the perfect location to explore El Centro and close to the Opera station so you can get around other areas you may want to see as well. I was able to quickly walk to Atocha station a couple of times and explore other parts of Spain without a problem too. This apartment is also equipped with great amenities which would make it perfect for a long-term stay. Despite being centrally located, it was really quiet at night and I never felt unsafe coming and going.
