Marlen and Alfredo are wonderful hosts with a great space in the most lively part of Madrid. Marlen checked in with us frequently to see how things were going, responding to any questions we had within minutes. The apartment itself is exactly as shown, lovely and well appointed. The street it's located on is buzzing, lined with fantastic restaurants and a popular theatre. There's also a wonderful little square just up the road that connects it to Gran Via. A grocery store no more than 30 seconds away (and directly across from our favourite restaurant) was also very useful. We would not hesitate to stay at Marlen's place again, and recommend it to anyone looking into visiting Madrid. Thanks Mar!
