Adriana's apartment is quiet, comfortable, and very clean. She was a great host - with easy communication and with provisions for any unexpected amenity needs (soap, etc). The fixtures are modern, despite the older building (shower, sink, etc). The decor is cool and well-balanced, giving the apartment an updated, special feel throughout. We enjoyed our stay there!
It is close enough to the J train, which we used daily, but also far enough away where you don't hear it. The traffic subsides later, and the area becomes nice and quiet at night. The rest of the building was quiet, too. Highly recommend!
Also - Like tacos? Try Taqueria Pantitlan just down the street! So good!
