Gisselle's flat was clean, central, and fairly priced! Very close to the museums as well as the 1 Metro line which can get you basically anywhere in the city. She was a great host, offered us towels and offered to let us use the kitchen at leisure and well as offered to help with any questions about Madrid. We didn't spend too much time at the flat because we were busy enjoying the city. I recommend staying here on a trip to Madrid.
