My family and I had a great stay at Nicolas beautiful apartment in Ave de Mayo. The living room view of Congress is breathtaking and the whole place is so wonderfully decorated with interesting and creative art that we felt inspiration in every room. His sister Nina was great and fast to respond. We needed extra hangers for the closet and she brought more right away. The building is very quiet and there is good places to have breakfast and dinner near by. Overall we had an excellent experience.
