Abraham and Paki are the best! They are by far the best hosts I have encountered through Airbnb. They are very friendly, helpful, and hospitable. The Oasis is clean and comfortable and the rooms are quite spacious. It is centrally located, near the Zocalo, el Palacio de Bellas Artes, and el Parque Alameda. Other parts of the city are easily accessible by metro or bus. I stayed with them for two weeks. If I do more dissertation research next summer, I will definitely be staying with them again.
