My son and I stayed at Marianne's place for 5 days to attend a colleague's wedding.
It was a great experience because Marianne's description of place, neighborhood are all true. A very clean comfortable apartment with a great wood floor, good furniture, functioning appliances, etc.
She is an excellent communicator on airbnb, WhatsApp, email, etc. She speaks several languages. In person, she is kind and helpful and ready to help on any issue a guest might have; fortunately, we didn't need it, but was good to know she was a call or message away. Her apt has a very useful hand-drawn map with places in neighborhood dealing with food, money, etc, for example, that we used a lot.
Thanks, Marianne, for your part in our excellent Buenos Aires experience.
