The best thing about this apartment is the location. It's less than 5 minutes from the closest subway station. There are lots of restaurants around the apartment. There is even a pedestrian shopping street close by. The kitchen is well equiped and if you want to cook, it is very convenient . There is also a supermarket very close by.
The only thing that potential customers would need to know is that the shower is extremely small. It measures about 26 inches on each side (66 cm square). If you are a big person, you may hardly fit in or you won't be able to turn while inside the shower.
The host is friendly and helpful with good communications before check-in giving very good information on how to get there. I would definitely consider staying here again if I come to Madrid again.
