We stayed in Buenos Aires for 10 days and had a wonderful time. The RentInBA team was very responsive and helpful. The listing said 4 beds but there were only 3 on arrival. When we talked with the team they quickly brought an additional bed.
The apartment is bright and clean. There is cable tv and good WiFi. The kitchen is a bit sparse with cooking equipment. There are 4 cups, 4 wine glasses, 4 plates, and 4 bowls. Air conditioning is in only 1 bed room and the main room.
The building is quite nice with a friendly security staff. There is a pool and 2 parrillas that you can use. Make sure to sign up for a parrilla time with security. It is not guaranteed. The 16th floor has a gym with an incredible view of the city. There is laundry in the building but you must buy finchas lavados to use the machines. We got them at a kiosko a few blocks away.
Overall a great stay. We would come back!
