We enjoyed our stay at the apartment. The location worked perfectly for us - it was a 10-15 minute walk to most locations in the center, 2 min walk to San Telmo, and a quick taxi ride to more remote locations in the northern areas of BA. Luis is a great host - he was able to arrange airport transfer for us on 24 December, and left some fruit and wine for us at the apartment. The porter at the house is very helpful. The place is perfect for a short stay.
