Cesar was a good host. He replied to our messages quickly and was accommodating. The apartment is as described. The WiFi works well, as does the air conditioning. Opening the large window in the bedroom, and the windows in the bathroom and kitchen provides a nice cross breeze. The apartment feels secure. And if you can navigate the transit system it is not very difficult to access other areas of Buenos Aires. It is also possible to walk to San telmo, and the port, for example. As long as you are physically capable. We had a great stay. No complaints, gracias cesar! ( cesar also arranged a taxi from the airport with jonathan. He was a really friendly guy)
