The apartment was sparkling clean and had all the amenities we needed. The bed was comfortable, the linen was soft and luxurious, and the kitchen had all the pots, pans, dishes and utensils we needed to cook.
The apartment is right off a fairly busy square in the heart of the city. It was very easy to walk to all the major destinations. We didn't need to drive or take the metro.
Overall we had a great time in Madrid and our stay was very comfortable.
