The location is everything! The apt building is a 3 min walk from Sol (plaza & metro) and right off of Plaza de Canalejas. 10 min walk to art museums, 15 mins walk to Atocha station, 8 min walk to Plaza Mayor. There are great coffee shops and gems of restaurants within 5 mins walk. La Finca de Susana restaurant is right on the street of the apartment (10 Principe) — make a reservation for dinner. It’s a spacious apartment for 2-3 people! There is a queen sized bed & sofa bed. The sofa bed is noisy/creaky if you move around on it but it works fine for a petite or small sized person. Hosts were super helpful and gave us detergent to do laundry. Highly recommend staying here if you want to be close to a lot of major sites & night life! It wasn’t noisy at night for being in the center — the two large windows are pretty soundproof.
