We had a very nice stay Joaquín and Natalia's apartment. The place is extremely central, and the hosts had many great recommendations about sights, activities, and restaurants around the city. Apart from a small issue with our check-in -- we arrived an hour earlier from the airport than their estimate and they were not able to meet us until close to the original time -- communication was thorough and timely. The apartment is spacious, the kitchen well-equipped if you plan to cook, and we found everything to be immaculately clean.
