Ambar's place is a clean, tastefully-decorated home base from which to explore the upscale Roma and La Condesa neighborhoods on foot. This penthouse pied-a-terre accessed from the roof (!) comes replete with a hammock—what's not to like?? If you need to cool down, the apartment has an ample ductless AC cooling system. As it is right on Avenida Insurgientes, a major thoroughfare, and conveniently located (there's a Metrobus/bus rapid transit stop RIGHT in front of it), it can get a bit noisy, especially when the windows are open, but it's not intolerable, and I slept just fine, especially when using the complimentary ear plugs provided.
Overall, great stay!
