Great apartment, really enjoyed my stay. I stayed there 4 days on my first trip to Madrid. It’s well located to all the main sights as well as the metro. It’s pretty quiet despite being a few blocks from a main street and near attractions (bring earplugs is you are a light sleeper and staying in the living room Murphy beds). One thing to note is the apartment on the ground floor. Wonderful bakery just down the street and cute little boutique shops and restaurants nearby.
Apartment was clean and comfortable.
Javier was a very responsive host and answered any questions I had quickly. Highly recommend!
