Arianna's place is in the most beautiful tree-lined neighborhood of CDMX ... close walking distance to cute cafes, amazing restaurants, markets, and the forest! Her instructions for check-in were very detailed and helpful, including photos of every single step. We didn't get to meet Arianna but felt communication up until that point was great.
That said, the photos look a lot better than the actual apartment. In reality, it was dark (not somewhere you would want to relax or hang out inside ... thankfully we had plenty to do outside all day and night), and it was pretty dirty. The floors and carpets hadn't been cleaned, and there was hair all over the shower. Additionally, we were staying for 9 days and we only got one roll of toilet paper and one hand towel. At least there was a convenience store across the street so we could buy more.
Many reviewers mentioned the hot water being an issue, but it wasn't for us. Showers were plenty hot :)
Overall, Arianna's place was totally fine, but just be aware the photos make the place look brighter, cleaner, and better decorated than it actually is.
