We had about a month long stay at Christianne's place and really enjoyed our stay! The place is spacious with lots of natural sunlight. Rooms are big with large closets and beds are comfy. Kitchen had just the right amount of amenities though we did eat out everyday so can't say we used it for much besides making tea occasionally and storing leftovers. There's a convenience store right downstairs for snack/drink needs and an OXXO at the corner. The home is also beautifully decorated.
Location was great for us. Close enough for us to the main street, walkable distance to a few parks, and convenient to many great restaurants and bars. On Fridays there's lots of street vendors just one block away which we enjoyed as well. We took Ubers everywhere so can't speak to the place's proximity to local transportation. Keep in mind that if you're staying in Roma Norte, there will be lots of tourists/foreigners around.
Two small issues we had during our stay:
(1) In the middle of the night, typically on the weekends, sometimes there would be extremely loud noises (dogs howling, music blasting, etc.) which would wake us up and didn't provide for restful sleep. There were also loud noises for during the day periodically which a bit bothersome while working from home (typically construction but sometimes loud music as well).
(2) We found around 5-6 small cockroaches in the kitchen during our stay. They were small so didn't bother us too much but just a heads up.
