My wife and I stayed 4 nights in the apartment of Andres. I can not think of anything negative or critical to say about the place. It was super clean, decorated very nicely, had just enough eminites, the beds were SUPER comfortable, it was quiet at night, and I felt very safe. The location is perfect if you want to stay in the old city center, surrounded by history and the hustle and bustle of a city with 8 million people. But like I said, once inside the apartment you don´t feel like you are surrounded by millions of people. The host Andres, is one of the nicest and most helpful person I have every met. I would recommend this place to anybody, and I would stay here again, without a doubt.
