I was in Buenos Aires for a conference and board meetings, and later joined by my adult daughter for our vacation starting point. This location was central to my hotel events as well as prime tourist attractions, and walkable!
This listing is in a great area of historic Puerto Madero and feels safe for solo travelers. It is on the second floor of a well maintained and upgraded building with an elevator, indoor swimming pool and sauna (didn't use), and helpful and friendly doormen. The apartment was exactly as listed, clean, comfortable, and it felt more spacious than the photos suggest. It is near a rail crossing, so bring ear plugs as I did if you are a light sleeper. My daughter did not need ear plugs to sleep.

Luciano was a marvelous host in all respects! This included: waiting for my late arrival (travel delay), communicative via WhatsApp and email, helpful with great travel suggestions, lent me a phone adapter/charger as mine got left, and later stored our luggage after check out prior to a late night travel departure!
I would highly recommend this listing and would definitely stay here again! Lastly, although I am fluent in Spanish, it is a huge bonus to know that Luciano speaks good English:-)
