I stayed at Maria's place for a month in February and cant speak highly enough about my experience. The apartment is in a new building and a great location right in the middle of San Telmo and Puerto Madero. Maria was extremely helpful and always responded to me within minutes whenever I had a question or needed help. The apartment is clean and was perfect for me as a single tenant. The roof of the building is really nice with a big area to relax and a small pool on warm days. I would highly recommend Maria's apartment to any future travelers! Thanks Maria!
