Had a really great 5 night stay here at Casa Kamffer. Only wish I could have stayed longer. The place is just as described. It's super clean with everything you need for a pleasant stay. Cuauhtemoc is an excellent host. Very friendly to chat with, and has expert tips about things to do and see in the city. Safety is a priority for the place and the set of keys you're given and instructions how to use them confirms this. The neighborhood is incredible and safe. Plaza Rio de Janeiro directly outside the front door which is a gem and restaurants, bars, supermarket, bakeries, street vendors, Metro, Metro Bus and so much more right at your fingertips.
