I really loved Lucero's, Casa Lucero. It had everything I needed and I loved the thoughtful touches like slippers, robes, and more. The place felt really homey and was perfect for relaxing after exploring the city. Lucero is also a wonderful host and makes herself reachable and is happy to provide answers to questions or provide recommendations. I would definitely stay at her place again! Note that Mexico City can sometimes be loud in the morning (random construction, random car noise, etc) so I would suggest bringing ear plugs if you are a light sleeper. I am a heavy sleeper, so I wasn't affected too much, but just an fyi for folks visiting the city. In general, the area was quiet and very convenient, though!
