A great apartment with good kitchen facilities. Rooftop balcony was a nice relaxing space after exploring Madrid all day to enjoy wine/dinner.
Nelson Mandela place gets noisy at night and security questionable at that end of the street. Apartment windows block most of the noise though.
The hot water system/boiler wasn't working but the hosts were quick to call a technician to fix the problem. Overall a comfortable apartment and big enough for a family.
