My friend and I had a wonderful stay at Carmen's place during our first trip to Madrid! The apartment is just outside of Malasana which, in my opinion, is an excellent location because it was far enough from the nightlife to not be too noisy but still had a good number of restaurants nearby and in walking distance to the metro, bars, etc. The apartment was very spacious and we were left with coffee, water and snacks. Mylene was our contact and she was very prompt with checking us in and answering all of our questions. We'd definitely recommend this place to anyone visiting Madrid!
