Maria's place. There are some pros and cons. Let me start with the positives.
Pros:
-Great Location (center of city)
-Jesus (local) was there to greet us and showed us how to use the water heater. He also helped with recommendations and set up our taxi back to the airport. He was always available.
-Kitchen had dishes
-Refrigerator available
-Stove available
-provided playpen
-quiet
Cons:
-There is NO ELEVATOR and it's on the 4th floor
-The water heater which also was the heater kept having to be reset
-The floors were slanted and beat up (luggage kept rolling)
-Dusty possibly mold?
-Place was small
-Not kid friendly
-TV is located in a weird spot so you can't really use it
-The key was temperamental have giggle it to open main building door and apartment door.
-The building was being painted and had a strong chemical smell.
Overall, our stay was pleasant. The customer service was on point. I would recommend this place for the location alone. Madrid was a great place to visit.
