Agustín and David were excellent hosts. They responded almost immediately to all messages.
The apartment is much bigger than I expected, and had more than enough space and ammenities for two people. The space was really cute and comfortable. The building has an elevator and a friendly security guard/ doorman, and the neighbourhood felt very safe. It also happens to be above one of the best restaurants in the city. My only note would be that the apartment is street-facing and traffic can be hectic in Mexico City. So if you are a little sensitive to noise or light from the street, earplugs/an eye-mask should help! But we were very comfortable, and didn’t have any problems with this. We would definitely stay with them again!
