We had a great time at Neiva's place. We were worried since we were travelling on schedule and arriving late on the evening: Neiva managed to get the key for us and clean the apartment with only a few hours notice.
The location is excellent, heart of San Telmo, a walk away from Puerto Madero. Also really safe neighborhood: the police station is near, so you can expect a lot of police walking around.
The communication with her was superb, she answered our calls and offered her help at all times.
She's someone you can trust and feel safe. It was a great pleasure to meet you Neiva!
