Best place to stay in Madrid. Its right in the center of everything, nothing was more than a 15min/ 20min walk. Two flat screen TVs with Netflix and complimentary wine / coffee were amazing touches. The bed is also quite comfy. The apartment was so nice I wanted to extend my stay.
Note on opening the door: have to turn the door knob quickly and firmly to the left and then forcibly turn the nob through the hitch and push the door. Be careful as the rim around the nob is quite jagged and we cut ourselves.
