The Stay is in a very central location, walking distance to Palacio de Bellas Artes. It was towards the end of the leg of our trip and we were very tired so we took an Uber, but you should also be able to walk to the Zocalo and other attractions nearby as well! Lots of food stands and sellers once you turn and walk on the main road.
Luis was very accommodating and responsive to us with a special request, which we truly appreciated. The bedrooms and bathrooms were as pictured, but the common areas were better in person than in the photos :-). It had great amenities for an extended stay, a full equipped kitchen, board games, and I believe I spotted Metro Cards you could use. The small balcony was very cute and great to drink a morning coffee (especially in great Spring weather). We enjoyed our stay!
