Great location, close to anything in Madrid. Great hosts.
I spent a couple of weeks here and this place was perfect for my needs. Close to many attractions, easy to work remotely with a fast speed internet. Great night life.
Few things to consider:
This is a fourth floor with no elevator.
Madrid is noisy 24/7. This place is less noisy than others in the neighborhood since there are no businesses downstairs but you will still hear some street noise 24/7.
Other than that, this place is perfect for singles or couples who want to explore Madrid (charming and friendly city!)
