Marlen was a fabulous host. She was on call the entire time and helped orient us to the neighborhood, book reservations at restaurants and clubs, and gave us lots of helpful suggestions about sightseeing in and around Madrid. The apartment is located in a very trendy, busy neighborhood with hundreds of cafes, bars and restaurants within walking distance. Easy access to metro and all major attractions. The apartment was new, very clean, and modern. You will love staying in Marlen's apartment and Madrid!
