Abraham's oasis is a warm community for the Mexico city bound. The location is walking distance to the Hidalgo metro, alameda and calle reforma. There are great food vendors in the neighborhood! Try to find the gentleman that sells arroz con leche and tamales de mole. During my stay, the house was full of travelers, coming and going. I think Abraham stated 10 other people in total! Thus it can become a tad noisy, especially if your room is sharing the window with the outdoor terrace. If you tend to be a light sleeper, bring some ear plugs and you should be fine.
The oasis is a comfortable, enchanting and a good place to stay. It's clear that Abraham puts lots of thought and energy into creating the oasis.
