This is a really great stay to explore Centro Histórico and its surroundings. The studio was clean with a comfortable bed, great rain shower, and delicious coffee. It felt safe at all times, and you're about two blocks away from the Bellas Artes metro stop. There's also a cute cafe next door where you can grab breakfast. During my stay, noises came mostly from within the building. I think the architectural style amplifies noises, but it wasn't an issue for me. Good nearby eateries I'd recommend are Mata Comedor Cantina and Pizza and Love.
I would definitely stay here again. There's so much I didn't get to see during my short trip. ¡¡Gracias, Flavia y Mauricio!!
