Overall, staying at Andres' was wonderful. There's great light in every room, the location is perfectly situated in Condesa, and the space itself is beautiful. Andres was communicative and understanding when I messaged him with questions, as was Acela who came and cleaned the apartment weekly.
Staying at Andres' for an extended period (5 weeks) and working remotely was difficult because of the noise. The walls are very thin in the apartment and outside noise can be heard in every room, especially because its a busy street and because of the two restaurants downstairs. There was also construction happening on nearby buildings. What made the experience more challenging was the construction going on in the lobby and courtyards of the apartment building itself for the entire duration of my stay. It was extremely loud in both the living room and bedrooms daily and taking meetings with drilling noises was not sustainable. Had I known that there'd be construction in the building the entire time, I likely would not have stayed there.
Other smaller things to note for transparency: the wifi is spotty in both bedrooms and was sometimes inconsistent in the living room. There were ants in the main bathroom and smaller bedroom.
