Antonio's apartment was in a great location and looked just like the photos. We were able to walk or metro everywhere easily from the apartment - couldn't have asked for a more centrally located spot! Antonio was very nice and was waiting for us when we arrived to help us get upstairs and get the keys.
Our only complaint was that the WiFi was quite bad. The signal really only worked in the living room (right near the router) and we had to reset the box a couple times a day to get it working, which was frustrating since we were relying on it to avoid going over international data limits. Just something to be aware of if you also plan to rely on WiFi during your travels.
