We had a great stay at Maria's place! We didn't get a chance to meet Maria in person but her friend Aarón was extremely helpful and welcomed us in the best way. The apartment is just the way it looks on the photos – spacious, bright, clean and well-equipped. There were also nice surprises such as heating and a filter which lets you drink water straight from the tap. The building is modern and safe and from the 5th floor you get great views, we even saw the volcano Popocatepetl one afternoon! The neighborhood is not the most exciting in the city but you have everything you need in the area and it's easy to reach most parts of the city. One minor drawback is that the metro is quite a long walk away.
