Ernesto's place has everything a solo traveler or couple might need. Check in is easy, the wifi is solid, the hot water is the best I've had in Mexico City, and the location, for me, is unbeatable. At night there may be a bit of noise from the cafes and bars below, but it was not at all problematic. In fact, I found the happy hum to be pleasant. Ernesto's easy to reach and quick to respond. Plus, this place features the only walk-down closet I have ever seen.
