I would recommend Salvador's place to anyone looking for a beautiful and easy stay in Mexico City, for either short term or long term.
I fell in love with the place and ended up staying here for months while working and living in Mexico City, and I'm so happy I did. It has beautiful architecture and light -- plus it's clean, peaceful and located right by what ended up becoming my favorite restaurants and coffee shops in the city. Make sure you try the juice shop across the street, coffee shops on the street, plus Tamales Madre next door and Cicatriz around the corner :)
The main living area opens up big doors to the beautiful outdoors space, so it was nice to have this while I was working inside. There is also a full kitchen setup so I could do a lot of cooking and baking at home. Plus, Salvador was an amazing communicator and also such a kind host which made all the difference.
