The place is at the end of one of the coolest neighborhoods in the capital. You can walk to the metro or walk trough the whole area as a nice way of spending your time there. For vegans: there’s Huerto Roma by walking distance and it’s vegan mekka ;)
Maria Antonieta is very helpful, she has the house rules that you need to follow, but nothing extraordinary.
Make sure to ask her to share location from G. Maps since it’s not easy to get there, but once you save the location, you’re good :)
