I stayed at Alberto's for 20 days.
First, the apartment looks exactly the same as photos, so you know what to expect. The space is very tidy, and there are ladies that provide cleaning. You have your own bathroom, and kitchenette with a fridge where you can cook meals.
Second, the location is fantastic. The Airbnb is located very centrally, right next to the Hidalgo metro station. There is an Oxxo convenience store right downstairs, and various local restaurants and shops steps away.
Lastly, the hosts are very kind and caring. If you have any problems, they will correct it to their best potential. They will give you information and tips about the city. Senor Alberto is also fluent in English.
When I return to Mexico City, I will definately book here no doubt. What a fantastic trip I had thanks to selecting a great place to stay!
