Bertha & Kazu's place is in the most perfect location in Roma Norte. It is so large and spacious, with every piece of furniture, utensil, or toiletry you could need. You can easily walk to nearby neighborhoods, the metrobus is right around the corner, and there are always Ubers in the area. There are tons of restaurants down Orizaba and Alvaro Obregon, too. The beds are firm, so if you prefer something soft, you can use their extra comforters to pad yours. I sleep hard so the nearby restaurants didn't bother me, but about Thursday-Saturday there is some music playing down the street. You could also just use ear plugs if you're a light sleeper (though for a megacity, this place is really quiet). The only downside is the shower that you have to manually drain with a mop, but I would totally overlook that because it is a warm, sunny, comfortable, and large space, so totally worth it!
